Safety ¡ WARNING: Laser light presents a severe eye hazard and a potential for burns or fire. The system’s aiming beam may be viewed by an unprotected eye. Never activate the system treatment beam without eye protection. It presents a severe eye hazard if viewed directly or by reflection. Avoid exposure to the laser beam. Take all necessary protective measures in areas where the laser is being used. Introduction This section describes specific laser hazards and appropriate precautionary measures. Guidance for the safe use of lasers is given in IEC 825-1. It is also given in two equivalent American National Standards. The first is ANSI Z136.1-2000, The Safe Use of Lasers, and covers general use of lasers. The second standard is ANSI Z136.3-1996, The Safe Use of Lasers in Health Care Facilities, and covers specific use of lasers in medical applications. Refer to the general ANSI Z136.1-2000 standard for the actual calculations for eye protection. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. S CAUTION: Changes or modifications not expressly approved by Laserscope could void the user's authority to operate this equipment. EYE INJURY RECOMMENDED PRACTICE V: ALL PEOPLE IN THE NOMINAL HAZARD ZONE SHOULD WEAR APPROPRIATE EYEWEAR APPROVED BY THE LASER SAFETY OFFICER.1 Visible light and near-infrared laser energy passes through the transparent components of the eye (cornea, lens, aqueous and vitreous humor), and is focused on the retina. This light can cause an accidental retinal burn. The degree of injury to the eye will depend upon the power of the beam, how focused the beam is, and how long the eye is exposed to the beam. 1 2006 Standards, Recommended Practices and Guidelines: Recommended Practices for Laser Safety in Practice Settings. AORN. Denver 2006: pg 565-570 Safety vii
viii Operator’s Manual Precautions against eye injury should include wave-length specific laser protective eyewear for the operating room staff. Patient’s eyes and eyelids should be protected from the laser beam in a method deemed appropriate by the laser safety officer. 2 See the Eye Protection Information Guide in this section for more information regarding eye protection. Laser eyewear is not interchangeable for a variety of lasers. Eye Protection Information Guide It is the responsibility of the hospital or medical institution where the laser surgery is performed to establish a written policy on eye protection. Several articles have been published stating the strong OSHA and JCAHO (Joint Commission on Accreditation of Hospital Organizations) position to adhere to ANSI Standards. Refer to ANSI Z136.1-2000 and ANSI Z136.3-1996, in conjunction with the recommendations of your Laser Safety Officer (LSO) to develop your facility’s laser policy. This guide will address some common questions raised on the issue of laser eye protection. The information contained in this guide is designed to assist you in tailoring a policy to fit the needs of your institution, particularly in relation to the use of the GreenLight HPS™ laser system. Laser Protective Eyewear There are several products available for use with the GreenLight HPS™ laser system to protect both eyes and video equipment. This section describes the laser protective eyewear and the video camera filters that have been designed to meet ANSI Z136.3-1996, ANSI Z136.1-2000 and DIN standards for safe viewing in a medical facility. All the filters have optical densities greater than 5.0 at 532 nm. The OD of the filters indicates how much the light is attenuated and is defined as: Optical Density = OD = –Log10 (Filter Transmission) A filter with an OD of 2 has a transmission of 1/100 or 10-2 while a filter with an OD of 5 has a transmission of 1/100,000 or 10-5.  NOTE: It is required for everyone in the room to wear protective eyewear. 2 American National Standards Institute, Laser Institute of America, American National Standard for Safe Use of Lasers in Health Care Facilities. (Orlando, FL: The Laser Institute of America. 1996)
Safety ixTwo different types of eyewear have been designed to protect operating room personnel from the GreenLight HPS™ laser energy. These include: • The Surgeon Glasses (catalog number 10-1350 and 10-0008). They have a min. optical density (OD) of 5.0 at both 532. The essentially clear lens material has very high visible light transmission and minimal color distortion. • The 532nm Surgeon Protective Goggles (catalog number 10-7030). Have a min. optical density (OD) of 5.0 at 532 nm. Although they have good visible light transmission, the orange color of the plastic lens causes some color distortion. Eye Protection Product Reorder Information • 532nm Surgeon Protective Glasses, Large Frame (catalog number 10-0008) • 532 Surgeon Protective Glasses, Small Frame (catalog number 10-1350) • 532nm Surgeon Protective Goggles, Standard Frame (catalog number 10-7030)
x Operator’s Manual COMMON QUESTIONS ABOUT EYE PROTECTION 1. “O.D.” is marked on the laser eyewear. What does it mean? O.D. stands for optical density. It is specific to the spectral wavelength marked on the eyewear and represents the capability of the eyewear to block out laser light. The higher the O.D., the greater the amount of light blocked out. The O.D. marked on the eyewear is sufficient to provide protection for the use described in the associated product insert. Eyewear is not interchangeable for different wavelengths. Eyewear designated for use at 532 nm should only be used when viewing the 532 nm wavelength. For more information about the O.D. of Laserscope’s eyewear, consult the product insert shipped with the specific eyewear. 2. Why is the eyewear for the GreenLight HPS™ laser system 532 nm laser tinted? The human eye is very sensitive to light in the green portion of the spectrum. Since the GreenLight HPS™ 532 nm laser system operates in the visible green light wavelength, protective eyewear for 532 nm must block a portion of this green light to provide adequate eye protection. 3. Does my eyewear protect me if I can see green light during lasing? Laserscope eyewear is designed to block out a specific portion of the light spectrum in green, and allow other parts of the spectrum to pass through. There is nothing dangerous about viewing green light at low intensity or the red aiming beam. The eyewear is designed to protect against the high intensity of the green laser light used to perform surgery. 4. Why do goggles fog and what can be done to prevent this from happening? The fogging of goggles is a common problem experienced by many laser users. The warmth of the wearer, stress of the case, and coolness of the procedure room are ideal conditions for condensation to form on all eyewear, despite manufacturing design. The use of anti-fogging agents after cleaning and before each case should reduce the fogging problem. 5. What is the potential for a fiber to break during a procedure and cause eye injury? During normal use, a fiber may incur stress when it is inserted into the cystoscope. Stress is a concern when fibers are being used because small nicks in the nylon jacket of the fiber can result in increased fragility.
Safety xiThe probability that a person without eyewear will directly view a fiber breaking is low, but can occur. The probability of the fiber breaking while actually aimed at someone's eye is low. The following factors must all occur simultaneously in order to result in hazardous exposure: • • • • • • • Alignment of the laser beam with the eye Close proximity of the eye to the source of the laser light Exposure time in excess of damage threshold With proper use of the laser equipment, the chance of these events occurring simultaneously is remote, but may occur. Laserscope supports the ANSI recommendation that all personnel in the operating room wear appropriate eyewear when the laser is being used for open or endoscopic procedures. 6. Do I need laser eyewear with endoscopic cases? Yes, protective eyewear is routinely required for most laser cases. In an editorial article published by Rockwell Laser Industries, the use of eye protection during endoscopic laser surgery was addressed. According to Rockwell’s interpretation of ANSI Z136.1 (Section 4.3.6.2), Class 1 conditions shall be considered as fulfilled for those limited open beam path lasers or laser systems where measurements and analysis confirm that the accessible levels during operation are at or below applicable maximum permissible exposure (MPE) levels. By this definition, endoscopic laser surgery (ruling out the possibility of a broken fiber) could be considered a Class 1 condition. Laserscope supports the ANSI and AORN recommendations that protective eyewear be available and worn during all laser procedures by all personnel present. 7. What are some appropriate ways to protect the patient’s eyes during laser surgery? The patient should always be educated on the laser procedure and eye protection requirements prior to the start of the procedure. In addition, the following protective measures should be taken: Use moist towels where appropriate. If the patient is awake, use suitable protective eyewear, and instruct the patient not to remove the eyewear. If the patient is anesthetized, lubricate and tape the patient’s eyelids shut. Use a combination of moist towels, gauze eye pads, eyeshields, and drapes to protect the eyes when the surgical site is on or near the face.
xii Operator’s Manual 8. Where can I find additional information about eye safety and protection? Current literature on laser applications is available in medical libraries. Additional information on terms, definitions and reference materials may be obtained by reviewing ANSI Z136.1-1986 and ANSI Z136.1-2000 and ANSI Z136.3-1996, or by contacting: • • Laser Institute of America 12424 Research Parkway, Suite 130 Orlando, FL 32826 Phone: (800) 34-LASER or www.laserinstitute.org Rockwell Laser Industries P.O.

Safety xiii BURNS RECOMMENDED PRACTICE VIII: ALL PERSONNEL IN THE LASER TREATMENT AREA SHOULD BE PROTECTED FROM FLAMMABILITY HAZARDS ASSOCIATED WITH LASER USE. 3Personnel using lasers should be knowledgeable of the fire hazards associated with laser use. Accidental irradiation of tissue other than the target tissue may result in a burn or vaporization, regardless of the wavelength. Surrounding the target area with moist drapes or saline-soaked sponges will keep it moist and greatly reduce this hazard. Flammable or combustible items in the laser environment may include: flammable liquids or combustible ointments, gases, plastics, paper or gauze materials, adhesive or plastic tapes, and endotracheal tubes. Laser appropriate fire extinguishers and water should be available where lasers are utilized. Care and precision in aiming and applying laser energy is of paramount importance. ¡ WARNING: Never use a clamp to secure the laser fiber optic to a drape. The use of a clamp to secure a fiber may cause the fiber to bend at sharp angles and damage the fiber. To do so can result in an unsafe condition. The fiber can break and release laser energy causing a burn in the protective jacket. If undetected, this condition will result in a burn or ignition of flammable materials. When using the fiber with the laser, the fiber device connector should never be allowed to touch the floor or any wet surface. If the fiber connector does contact a surface other than the laser device port, dispose of the fiber in accordance with hospital safety regulations. REFLECTION OF THE BEAM FROM INSTRUMENTS RECOMMENDED PRACTICE V: ALL PEOPLE IN THE LASER TREATMENT AREA SHOLD BE PROTECTED FROM UNINTENTIONAL LASER BEAM EXPOSURE.ibidCare should be taken when aiming the laser beam to prevent reflection of the beam off metallic surgical instruments. Mirror-finish instruments are especially dangerous as they have highly reflective surfaces. The laser light reflected from such instruments is intense and potentially very harmful. Matte, dull, satin-finished, or ebonized instruments have less glare and those with curved surfaces do not reflect light as intensely. While these instruments usually produce a more diffused reflection that is less harmful, 3 2006 Standards, Recommended Practices and Guidelines: Recommended Practices for Laser Safety in Practice Settings. AORN. Denver 2006: pg 565-570
xiv Operator’s Manual this reflection can still be damaging. Protective eyewear should be worn at all times to prevent eye damage. ¡ WARNING: When using anodized, black chrome finished, or ebonized instruments during a surgical procedure, additional care should be taken to prevent burns. These instruments will become extremely hot when they come in contact with a laser beam and are not able to quickly dissipate heat. When any tissue is touched under these conditions, a burn may result. IGNITION OF FLAMMABLE MATERIALS The laser can ignite many materials used during a surgical procedure. Use of non-flammable materials is strongly recommended. See Operating Room Environment in this section for more information regarding flammable materials. VAPOR/SMOKE PLUME RECOMMENDED PRACTICE VI: PERSONNEL WORKING IN THE LASER ENVIRONMENT SHOULD AVOID EXPOSURE TO SMOKE PLUME GENERATED DURING LASER SURGERY.ibidThere is considerable concern about the biological plume created by electrocautery units, bone saws and lasers. Current medical literature recommends that a smoke evacuator and in-line filter be used to capture this plume. The plume should be regarded as a source of active biological material and a possible carcinogen. ELECTRICAL RECOMMENDED PRACTICE VII: ALL PEOPLE WORKING IN THE LASER TREATMENT AREA SHOULD BE PROTECTED FROM ELECTRICAL HAZARDS ASSOCIATED WITH LASER USE.ibidElectrical hazards with the laser are the same as with any electrical device. Care should be taken when plugging the unit into the wall outlet. The area must be free of water and your hands must be dry. Always disconnect the laser by grasping the plug and not the power cord. Examine the electrical cord routinely; if signs of wear are noted, contact the Laserscope Customer Response Center at (800) 356-7600 to have it repaired or replaced. When performing a surgical procedure that requires large amounts of irrigation, protect the foot pedal in a plastic bag. ibid ibid
Safety xvOPERATING ROOM ENVIRONMENT This section describes specific safety measures for the operating room to aid in the safe operation of the laser system. Laser Warning Signs RECOMMENDED PRACTICE III: ALL PEOPLE SHOULD KNOW WHERE LASERS ARE BEING USED AND ACCESS TO THESE AREAS SHOULD BE CONTROLLED.4The area where the laser is operated should be clearly labeled. Warning signs that specify the laser wavelength being used should be posted at all operating room and access-door entrances. Figure S-1 is an example of a sign suitable for use with the GreenLight HPS™ laser system. ¡WARNING: Warning signs are not interchangeable. Select a sign that is appropriate for the wavelengths in use. Figure S-1 GreenLight HPS™ laser system Warning Sign 4 2006 Standards, Recommended Practices and Guidelines: Recommended Practices for Laser Safety in Practice Settings. AORN. Denver 2006: pg 565-570
xvi Operator’s Manual Remote Door Interlock Always limit personnel in the operating room to those essential to the procedure. To protect intruding personnel from exposure to the laser beam, an optional remote door interlock can be connected from the laser system to the operating room entrance door. This interlock will automatically put the laser in STANDBY if the door is opened during a procedure. The laser will remain in STANDBY until the door is closed and the interlock is reconnected. Once reconnection is made, the operator can place the system back in READY and reactivate the surgical beam. The laser cannot be placed in READY unless the interlock is reconnected. If the use of the remote door interlock is desired, the biomedical personnel at the user’s facility can connect it. Access to the laser unit’s interlock is made via a socket located on the back panel of the laser (see Section 1.1. System Overview). Safety Recommendations The following are general safety recommendations for the operating room and are not specific to the GreenLight HPS System: • • • Keep drapes and towels moist to prevent their ignition and burning. Use non-flammable prepping solutions. Prevent combustion of methane gas by packing the rectum during perineal procedures.  NOTE: All lasers operate with a keyswitch. Keep the laser key in a designated place and allow only trained personnel access to the key. ¡WARNING: Do not fire the laser unless the aim beam is clearly visible and directed at the targeted tissue.

6 Operator’s Manual 1.2 GREENLIGHT HPS FIBER OPTIC Product Description The GreenLight HPS fiber (catalog number 10-2090) features a “side firing” mechanism delivering up to 120W of 532nm light to tissue. The fiber is guided to the treatment site by the continuous flow cystoscope, consisting of an inner and outer sheath set, 30º forward oblique telescope, and visual obturator. The GreenLight HPS fiber is used to cut, coagulate and vaporize tissue in endoscopic and open surgical procedures at a 70º forward defection angle to the fiber axis. It can rotate 360-degrees, allowing tissue access in multiple planes; and it is used in surgical applications where lateral delivery of laser energy is desired. GreenLight HPS fibers are sterile and designed for single use only. GreenLight HPS Fiber Optic Specifications Fiber size 600 microns Fiber length 12 feet (3.66m) Laser beam Side fire Sterilization Single use Fiber Optic Handling Guidelines If the tip of the fiber accumulates tissue debris during a procedure, turn the laser to STANDBY, remove the fiber from the cystoscope and carefully wipe the tip clean with moistened sterile gauze. The correct method of removing debris from the fiber is to gently wipe from the tip of the fiber toward the control knob. When the procedure is complete, dispose of the fiber using the standard hospital procedure for bio-hazardous material. GreenLight HPS fibers are single use devices and are not designed to be re-sterilized or re-used. S Caution: Improper cleaning of the fiber tip may cause damage to the fiber. Calibration Information GreenLight HPS fibers are tested at the factory to insure they have the proper transmission factor. They do not have to be calibrated by hospital personnel.
Introduction 7 1.3 GENERAL INSTRUCTIONS FOR USE 1. Remove the GreenLight HPS fiber optic from its sterile package using aseptic technique. Be sure to bend back all the tabs from the fiber package nest prior to removing the fiber. 2. Before starting the surgical procedure, the GreenLight HPS fiber optic should be checked for damage. 3. Connect fiber hub into the fiber port on the laser system console. 4. Place the laser in READY mode to activate the aim beam. CAUTION: Do not press the footswitch while checking the aim beam. Place the distal end of the fiber on a non-reflective sterile surface and turn slightly until the aim beam can be visualized. If the aim beam is not seen, the fiber may be defective and should not be used. 5. Check for kinks or bright areas along the entire length of the GreenLight HPS fiber. Do not use the fiber if it has been damaged. 6. Once the GreenLight HPS fiber has been checked, return the laser to the STANDBY mode. 7. Position the GreenLight HPS fiber optic at the targeted treatment site. The tip of the GreenLight HPS fiber should be in clear view and extended approximately 1 to 2 cm. beyond the distal end of the endoscope. The output beam of the fiber is aligned with the raised surface on the handle. Therefore, the direction of the laser energy can always be determined. 8. Place the laser in READY mode to enable the footswitch control. 9. Laser software automatically corrects for fiber losses such that the power level shown on the system video display indicates the actual amount of power delivered to tissue. 10.Treatment times vary based on distance to tissue, power settings, and other factors. The fiber should be maintained at a distance of 3 mm from the tissue for maximum vaporization. The efficiency of vaporization will decrease with increasing distance from the tissue and coagulation may result. 11.Avoid contact of fiber tip with tissue. If, during the procedure the tip accumulates debris, turn the laser to the STANDBY mode, remove the GreenLight HPS fiber from the cystoscope, and carefully wipe the tip clean with a sterile gauze or towel. Begin at the end of the fiber and wipe along the fiber tip. 12.Never bury the cap of the fiber in tissue while firing the laser.
8 Operator’s Manual 1.4 STERILIZATION Laserscope recommends that GreenLight HPS fibers be used in only one surgical procedure. The GreenLight HPS fiber is a sterile, single-use, disposable device and should not be re-used or re-sterilized. After the completion of the procedure, dispose of the GreenLight HPS fiber following the standard hospital protocol for bio-hazardous material. The GreenLight HPS fiber is ethylene oxide sterilized and is not designed or certified for multiple use. Do not re-sterilize. Do not reuse. ADDITIONAL INFORMATION ABOUT REUSING THE GreenLight HPS FIBER If you need more information on this subject, we recommend the AAMI Technology Assessment Report on the Re-Use of Disposables. It can be ordered from the Association for the Advancement of Medical Instrumentation at: (703) 525-4890 (Part Number: TAR6-058). Other questions can be directed to the Laserscope Customer Response Center at (800) 356-7600 or (408) 943-0636. STORAGE The GreenLight HPS fiber should be stored under ambient conditions. WARRANTY The warranty for the GreenLight fiber optic covers only defects in the material and workmanship. Should you need to return this product, call the Laserscope Customer Response Center for “Return Authorization”. Instructions for returning a product to Laserscope are detailed in the Accessory Return/Repair Policy included with each device. ¡ WARNING: Never secure a fiber optic using a clamp as doing so can result in an unsafe use condition. Use of a clamp can result in the fiber optic being bent at sharp angles or fiber damage which, in turn, can also result in an unsafe use condition. The fiber optic can break causing a burn in the protective jacket and the release of laser energy. If undetected, this condition can result in a burn or ignition of flammable materials. When using the fiber with the laser, the fiber device connector should never be allowed to touch the floor or any wet or non-sterile surface. If the fiber connector does come into contact with a surface other than the laser device port, dispose of the fiber in accordance with hospital safety regulations.

Chapter 4 Physician Information 4.1 TRAINING REQUIREMENTS The GreenLight HPS™ laser system should be used only by practitioners who have been trained in its proper use. All users and support staff must have thorough knowledge of its operation and its effects. Users should familiarize themselves with this operator’s manual and with this device in a non-clinical setting before using it for the treatment of patients in a clinical situation. 4.2 INDICATIONS S CAUTION: Federal (USA) Law restricts this device to sale by or on order of a Physician. The GreenLight HPS™ laser system and accessories are intended for use in endoscopic (cystoscopic) 532 nm laser resection of the prostate for the treatment of benign prostatic hypertrophy/hyperplasia (BPH). The device is not intended to treat prostate cancer. The laser system has also been cleared for use on various other soft tissue applications including bladder tumors and urethral strictures. 4.3 CONTRAINDICATIONS The GreenLight HPS™ laser system and fiber optic should only be used by a qualified and trained surgeon. The use of the laser system is contraindicated for patients: • Whose general medical condition contraindicates surgical intervention • Where appropriate anesthesia is contraindicated by patient history • Where tissue (especially tumors) has calcified • For hemostasis of vessels over approximately two millimeters in diameter • Where laser therapy is not considered the treatment of choice • Bleeding disorders and coagulopathy • Prostate cancer • Acute urinary tract infection (UTI) • Severe urethral stricture Physician Information 21
22 Operator’s Manual 4.4 POTENTIAL COMPLICATIONS AND RISKS The same complications and risks that exist for conventional or traditional surgery exist for laser surgery. These include, but are not limited to, the following: Pain: Short-lived pain may occur immediately following endoscopic/ cystoscopic laser therapy and may persist for as long as 48 hours. Fever and Leukocytosis: Immediately after laser therapy, the patient may experience fever and leukocytosis, which are commonly associated with tissue destruction. These generally resolve without treatment. Cultures may be indicated to exclude the possibility of infection. Bleeding: Patients may experience bleeding at the site of the laser therapy during or after laser therapy. Post-treatment hemoglobin and hematocrit are recommended to assess the severity of the bleeding. Sepsis: Laser-ablated tissue may become infected after therapy. If a question of sepsis exists, a culture should be taken and other appropriate evaluations made. Perforation: Perforation can occur as a result of excessive exposure to laser radiation. Perforation can also occur from tumor erosion, or as a result of any endoscopic/cystoscopic procedure. To clinically diagnose perforations, patients must be closely monitored post-operatively through physical assessment of clinical symptoms, hematology studies as deemed appropriate, and radiography. Other complications may include: • Allergic reaction to medication • Ulceration • Edema • Chills • Urethral stricture • Delay in healing • Sloughing • Bladder neck contracture • Epididymitis 4.5 PRECAUTIONS • The GreenLight HPS™ laser system is a surgical device to be used by surgeons who have been trained in laser surgery through courses, preceptorships, and under the guidance of other surgeons knowledgeable in laser use. No claim is made that the laser will cure any medical condition. • No claim is made that the GreenLight HPS™ laser system will cure any medical condition, or entirely eliminate the diseased entity. Repeated treatment or alternative therapies may be required.
• The surgeon should become fully acquainted with the unique surgical effects produced with the GreenLight HPS™ laser system prior to clinical use. These effects include coagulation, depth of penetration, and cutting intensity. • Prior to turning the laser system on, operating room personnel and the patient should be wearing protective eyewear suitable for 532nm laser energy. • Laserscope has no clinical information or experience concerning the use of Laserscope’s laser systems on pregnant women or nursing mothers. • The risk of combustion, perforation, and laser-induced hemorrhage, all of which could cause serious or fatal complications, must be fully explained to the patient. • As with conventional endoscopic treatment, adverse reactions such as fever, chills, sepsis, edema and hemorrhage may occur following laser treatment. In extreme cases, death may occur due to procedural complications, concurrent illness, or the application of the laser. In the case of the treatment of BPH, reported adverse events have been: decreased or retrograde ejaculation; urinary retention; bladder neck contracture; urethral strictures; hematuria; renal insufficiency; incontinence; potential for re-treatment and shortness of breath. • Use of lower power levels and shorter exposure times are required in order to prevent thermal damage to underlying structures; for example, to thin-walled structures, such as the bladder. • The surgeon should carefully assess the target and surrounding tissue. Then begin at the lowest power, with short duration exposures. Note the surgical effect and adjust the settings until the desired effect is obtained. • Before operating the laser system, surgeons and all staff operating the laser should carefully read and become familiar with the Operator’s Manual. • Careful assessment of the target and surrounding tissue should be made, and appropriate power should always be used. • Tissue perforation can occur if excessive laser energy is applied. This can occur through the use of excessive laser power or the application of power for excessive periods of time, particularly on diseased tissue. • Aim and use the laser only on tissues that are in full view. • Extra caution should be used when lasing tissue in close proximity to known arteries, nerves and veins. • Flash fires can occur. A basin of water should be available in case a fire should occur. • The laser may not be effective for coagulation in massive hemorrhage situations. The surgeon must be prepared to control hemorrhages with Physician Information 23
24 Operator’s Manual • strident alternative non-laser techniques, such as ligature or electrocautery. • Alterations in surgical approach or technique may be required to accommodate laser use. • The surgeon should schedule follow-up visits in the same manner as for any patient undergoing such surgery with other modalities. • Use caution when treating patients who have had difficulty with previous endoscopic/cystoscopic procedures. • Extra precaution should be taken when radiation therapy and laser therapy are to be used concurrently, including more stringent post-operative monitoring. Clinical studies have shown that patients who have undergone radiation therapy present a greater risk of perforation or tissue erosion. • To avoid damage from the treatment beam or treatment beam backscatter, it is recommended that the fiber be fully in the visual field. Do not fire the laser unless the aim beam is visible and directed at the intended target.
Chapter 5 Maintenance Maintenance 25 Introduction The GreenLight HPS™ laser system has been designed to provide trouble-free operation with minimal maintenance. This section provides information on the routine maintenance and care required for these laser systems. The laser, cooling system, and control electronics are enclosed in a tamper-resistant console.

OPERATIVE RECORD TEMPLATE The operative record must be customized for each individual patient treatment. The document must not be used as a preprinted operative record. PATIENT’S NAME AND DATE OF TREATMENT. _____________________________anesthesia for the procedure was jointly selected by the patient and his anesthesiologist. The patient was taken to the operating room, placed in the dorsal lithotomy position and prepped and draped in the usual sterile manner. The prostate size was estimated to be _____ g during previous examination. A ___Fr continuous-flow cystoscope was connected to saline solution irrigation and inserted into the bladder without difficulty in the usual fashion. A preliminary cystoscopic examination was performed during which the ureteral orifices, bladder neck and verumontanum were identified. The GreenLight HPS™ laser was set at ___watts. The GreenLight HPS BPH™ laser fiber was introduced through the working channel of the cystoscope. The median lobe was identified and it was vaporized down to capsular fibers. The bladder neck was then vaporized as far laterally as possible to open up the prostatic urethra. The median lobe was vaporized from the bladder neck to the verumontanum. The left and right lateral lobes were vaporized from the bladder neck to the verumontanum,. Vaporization was continued until the capsular fibers were visualized or until the lateral lobes were adequately vaporized. The proximal adenoma was vaporized first, then the scope was withdrawn to the verumontanum and the most distal adenoma was vaporized, always ensuring that the verumontanum was well isolated. By serially vaporizing the obstructing tissue, a wide open prostatic urethral channel was created. A total of _______ joules were used during the procedure. During the procedure, any bleeding vessels were effectively controlled. At the end of the procedure, the bladder neck, ureteral orifices, and verumontanum were again inspected, and found to be intact, and without evidence of incidental laser beam damage. The bladder was filled with saline solution irrigation, and the continuous flow cystoscope was removed. External pressure was applied to the dome of the bladder to ascertain the quality of the urinary stream. A strong urine flow was achieved, with minimal evidence of bleeding. A ___Fr (5cc) Foley catheter to straight drainage was inserted. The patient was transferred to the PACU (Perianesthesia Care Unit) in good condition.
PRACTICE NAME HERE PRE-PROCEDURAL PATIENT INSTRUCTIONS 1. Call your doctor if your condition changes, or if you develop a cold, infection or fever. 2. Let your doctor know if you are taking any blood thinners such as aspirin, aspirin-containing medications, Coumadin® or Plavix®. Your doctor may recommend that you stop taking these medicines several days prior to the GreenLight HPS™ procedure. 3. Take any antibiotics as prescribed by your doctor. 4. Ask your doctor to write prescriptions for any medications he thinks you should take before the day of your scheduled procedure. This will allow you to have those medications “on hand” when you leave the surgery center, instead of having to depend on someone else to take them to a pharmacy for you. 5. Write down any questions you have about the procedure. Bring them with you. There will be plenty of time to answer your questions before, during, or after your procedure. 6. You may eat and drink as usual the night before. Your urologist or anesthesiologist may allow a clear liquid breakfast, depending upon the time of day your procedure is scheduled. If you are scheduled to have your procedure before noon, do not take anything by mouth after 12:00 midnight the night before. 7. Wear comfortable, loose-fitting clothing to the hospital or ambulatory surgery center on the day of your procedure. 8. Bring all medications with you on the day of the procedure. 9. Ask your urologist or the anesthesiologist if you should take your regularly prescribed medications on the day of the procedure. 10.Please plan to be at the hospital/ASC at least 2 hours prior to your scheduled treatment. Remember that you will also need to spend some time post procedure to recover from anesthesia prior to being discharged to home. If your doctor has indicated that you will need to stay overnight in the facility, please arrange for someone to pick you up the next morning at ______a.m. 11.Arrange for transportation home; you may not drive or operate dangerous equipment for 24 hours after the procedure. (If you have spent the night in the healthcare facility, you will still need to arrange for a ride home.) 12.If you have any questions, or cannot keep this appointment, please call: _______________________________ __________________________ Practice/MD/RN Name Phone Coumadin is a registered trademark of DuPont Pharmaceuticals Co., Wilmington, DE 19898 Plavix is a registered trademark of Sanofi-Synthelabo, Paris 75013, France
PRACTICE NAME HERE GENERAL POST-PROCEDURAL INSTRUCTIONS 1. You may need to wear a catheter to drain your bladder after the procedure, depending upon how much swelling your doctor thinks may occur immediately following the PVP procedure. This catheter is generally removed within 24 hours. 2. Do not drive or operate dangerous equipment for 24 hours following anesthesia. 3. Avoid beverages containing caffeine as they may cause bladder spasms. 4. Activity level: Take it easy for 2 to 3 days. Do not engage in activities requiring heavy lifting, gardening, bicycling etc. This will increase the pressure your abdomen puts on the bladder, and may result in blood in your urine. 5. Take all medications as directed. Typical medications may include: a. Antibiotic (prevents infection). b. Non-steroidal anti-inflammatory drug (reduces inflammation). c. A drug to reduce bladder spasms. d. Mild over-the-counter pain reliever as needed. 6. Do not engage in sexual activity for 2 weeks. 7. Unless you have been advised to limit your fluid intake due to another medical condition, drink one glass (8 oz. or 1/4 liter) of water for every hour you are awake, about 64 oz. (or 2 liters) per day. 8. Please call the office at ___________________________ to schedule a follow-up appointment. 9. Please call the office immediately if any of the following symptoms appear: a. Bright red bleeding in urine with a heavy clot. b. Fever over 101º F (38°C). c. Inability to urinate for more than 4 hours. d. Feeling of bladder fullness that does not go away after urinating.
