Summary

A total of 81 patients with symptomatic bladder-outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH) underwent visual laser ablation of the prostate (VLAP) using a right-angled firing neodynium: YAG laser. The mean pre-operative prostatic volume was 48.5 ml. All patients were discharged on the 1st post-operative day with an indwelling catheter. Two patients underwent a transurethral prostatectomy (TURP) after failing a trial without catheter on two occasions. Of the remaining 79 patients, 75 were evaluated 6 months post-operatively. Mean symptom scores (I-PSS) decreased from 20.9 to 5.8, the mean maximal urinary flow rate increased from 7.9 to 16.4 ml/s and the mean residual volume decreased from 88.1 to 15.6 ml. Several different methods of evaluating BOO from pressure-flow measurements were used and all showed improvement. All the above-mentioned parameters showed a highly significant improvement (P<0.01) at 6 months.
