Transurethral prostatectomy: a prospective randomized study of conventional resection and electrovaporization in benign prostatic hyperplasia

Abstract

Objective To compare transurethral electrovaporization of the prostate (TUVP) with conventional transurethral resection of the prostate (TURP) in the treatment of men with benign prostatic hyperplasia (BPH). Patients and methods Seventy consecutive patients with symptomatic BPH and a prostate size of max ), post‐voiding residual urine volume (PVR) and sexual function were also evaluated during the follow‐up. Results Patients of both groups were balanced for the different baseline variables. The mean (sd) operative duration of TUVP was 52 (12.5) min, significantly longer than that of TURP, at 39.7 (8.8) min (PPPmax and PVR improved significantly in both groups at all intervals of follow‐up and there were no significant differences between the groups during the follow‐up. None of 15 potent men undergoing TURP and two of 18 potent men undergoing TUVP complained of impotence during the follow‐up. Conclusions TUVP is as effective as TURP in the treatment of BPH in men with a prostate size of <60 g. TUVP has the advantages of less blood loss, less absorption of irrigant and a shorter hospital stay, but it had a significantly longer operative duration.
