Transurethral laser ablation of the prostate--long-term results

Continuing experience with the use of Nd:YAG laser-fibre prostatectomy over the past 4 years has produced encouraging results. Of the 198 patients we treated with the 60-W/60-s technique, 74 were available for evaluation after undergoing laser ablation of the prostate between October 1990 and July 1994. In all, 29/74 and 9/74 patients were available for 24 and 36 months of follow-up, respectively. The American Urological Association (AUA) symptom scores, peak uroflow (Qmax) rates and post-void residual urinary volumes show marked improvement. Following laser ablation of the prostate (LAP), complications have included 16 patients with post-procedural recurrent obstructive symptoms requiring revision. Three patients developed urinary tract infection, two developed bladder-neck stenosis, four fully anticoagulated patients with clot retention required blood transfusion and three patients had epididymo-orchitis. The results show a sustained reduction in AUA symptom scores and maintained improvement in peak flow rates and residual volumes, with stabilization of the above-mentioned parameters occurring within 12-36 months. The results demonstrate the continued durability of the outcome of LAP.
