Laser- and electrosurgery as a treatment modality of BPH: urodynamic evaluation of seven different techniques in 280 patients

摘要

Laser treatment of the prostate as an alternative for transurethral resection of the prostate (TURP) has evolved from a complicated troublesome procedure to a single office procedure. In this study, we compared the efficacy of different electrosurgical and laser techniques. The data of seven prospective studies in 280 patients were evaluated. The patients were treated for bladder outlet obstruction due to benign prostatic hyperplasia during the period from 1992 until 1998. Five procedures were offered using Nd:YAG laser light, including ultrasound-guided free beam, a free beam technique applying either a predetermined energy dose or a visually-guided energy does, contact laser prostatectomy and a hybrid method where free beam coagulation was followed by contact laser. Two procedures were offered using electrosurgery comprising transurethral resection and transurethral electrovaporization. The clinical outcome was assessed pre-operatively and 6 months post-operatively by free flowmetry, post-void residual, and Shaeffer obstruction grade. Results after 6 months are shown in the table below.
