This device is composed of a real-time 7.5MHz ultrasound transducer coupled to a Nd:YAG laser with a 1.064μm wavelength that fires through an intact intraprostatic balloon. A series of feasibility studies in 21 canine prostate glands was performed with a follow-up time to 3 months. Results indicate that the Nd:YAG laser in the 20 to 40W range at a pull rate of approximately 1mm. per second is an effective means of removing substantial amounts of canine benign prostatic hyperplasia. Transurethral ultrasonography was a reliable means of identifying essential landmarks and of controlling the laser. Prostatectomy by laser coagulation necrosis resulted in no bleeding or postoperative obstruction. Intraoperative irrigation fluids were not required, eliminating systemic volume related problems. © 1991 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByKabalin J (2018) Editorial: Laser Prostatectomy—What We Have Accomplished and Future DirectionsJournal of Urology, VOL. 154, NO. 6, (2093-2095), Online publication date: 1-Dec-1995.Costello A, Bolton D, Ellis D and Crowe H (2018) Histopathological Changes in Human Prostatic Adenoma Following Neodymium:Yag Laser Ablation TherapyJournal of Urology, VOL. 152, NO. 5 Part 1, (1526-1529), Online publication date: 1-Nov-1994.Suzuki T, Kurokawa K, Suzuki K, Nakazato H, Imai K and Yamanaka H (2018) In Vivo Effects of Transurethral Balloon Laser Prostatectomy on the Canine ProstateJournal of Urology, VOL. 151, NO. 4, (1092-1095), Online publication date: 1-Apr-1994.Bihrle R, Foster R, Sanghvi N, Donohue J and Hood P (2018) High Intensity Focused Ultrasound for the Treatment of Benign Prostatic Hyperplasia: Early United States Clinical ExperienceJournal of Urology, VOL. 151, NO. 5, (1271-1275), Online publication date: 1-May-1994.Kabalin J (2018) Laser Prostatectomy Performed with a Right Angle Firing Neodymium: Yag Laser Fiber at 40 Watts Power SettingJournal of Urology, VOL. 150, NO. 1, (95-99), Online publication date: 1-Jul-1993.McCullough D, Roth R, Babayan R, Gordon J, Reese J, Crawford E, Fuselier H, Smith J, Murchison R and Kaye K (2018) Transurethral Ultrasound-Guided Laser-Induced Prostatectomy: National Human Cooperative Study ResultsJournal of Urology, VOL. 150, NO. 5 Part 2, (1607-1611), Online publication date: 1-Nov-1993.Norris J, Norris D, Lee R and Rubenstein M (2018) Visual Laser Ablation of the Prostate: Clinical Experience in 108 PatientsJournal of Urology, VOL. 150, NO. 5 Part 2, (1612-1614), Online publication date: 1-Nov-1993.
