Laser Treatment of the Prostate Using the Urolase Fiber: The Dutch Experience

Abstract

Purpose Subjective and objective results were assessed after laser prostatectomy with the Urolase* fiber at 5 different centers in The Netherlands. *Bard Urological Division, Covington, Georgia. Materials and Methods Patients were evaluated with the international prostatic symptom score questionnaire, uroflowmetry and post-void residual volume measurements. Urodynamic investigations with pressure-flow analysis were performed at 2 centers. Results Data for 233 patients were evaluated. Overall significant improvement in mean international prostatic symptom score, maximum flow, post-void residual and urodynamic parameters was noted. Differences in outcome among the centers may be due to variation of technique or different selection criteria. Postoperative morbidity was significant, with irritative voiding complaints for 4 to 6 weeks in up to 50 percent of all patients and urinary tract infections in 21.1 percent. Conclusions Laser prostatectomy results in subjective and objective improvement, which is operator independent. Despite the observation that perioperative (intraoperative and immediate postoperative) morbidity seems less severe compared to transurethral resection of the prostate, there is a shift toward greater postoperative morbidity.
