Abstract

PURPOSE: Patients that had undergone transurethral resection of the prostate (TURP) for benign prostate hyperplasia (BPH) were evaluated to assess the influence of the amount of resected tissue on the symptomatic improvement.
MATERIALS AND METHODS
42 men, with symptomatic BPH that had undergone TURP, were enrolled in this retrospective study. 20 and 22 patients with prostate volumes equal or less 30ml (group I) and greater than 30ml (group II), respectively, were evaluated. The resected tissue weight (RTW) and the resected tissue weight ratio (RTWR) were taken as preoperative parameters. The percent changes in the International Prostate Symptom Score (IPSS) and in the Quality of Life, and the satisfaction score, were used as measures of the symptomatic outcomes. The symptomatic outcomes of the two groups were compared, and the correlations between the RTW and RTWR and the outcomes in each group assessed.
RESULTS
All the symptomatic outcomes of group II were more favorable than those of group I. There were significant correlations between the RTW (and RTWR) and all three outcomes in group II, but there were no correlations between groups I and II.
CONCLUSIONS
The patients with the smaller prostate volume (equal or less than 30ml in volume) had less symptomatic improvement after TURP, with no benefit in increasing the amount of resected tissue during TURP. It is recommended excessive resection for BPH should be avoided with a small prostate.
