Paper Abstract

We investigated the use of the 805 nm diode laser (Diomed 25 Diomedics, The Woodlands, Texas) in combination with a cylindrically diffusing fiber (Surgimedics, The Woodlands, Texas) to perform visual laser ablation of the prostate in 8 mongrel dogs. Each dog received 15,000 J of laser energy delivered to the prostate in one continuous dose of 25 W for 10 minutes. Gross and histopathologic examinations of serial sections of the prostate were performed at intervals from 3 hours to 7 weeks postoperatively. All dogs did well postoperatively with only one episode of urine retention 5 days after the surgery. Grossly, an ellipsoid zone of destruction with an average maximum diameter of 2.1 cm was present in all dogs. Histopathological changes in the prostate were similar to changes consistently reported for prostatectomies performed with similar dosimetry utilizing the 1.06 Nd:YAG laser. We believe this wavelength laser in combination with the diffusing fiber compared favorably with the Nd:YAG/sidefire fiber studies previously done in this laboratory with the added advantage of simplified operator technique, less postoperative complications and increased margin of safety.
