Impact of finasteride treatment on perioperative bleeding before transurethral resection of the prostate: a prospective randomized study.

In this preliminary, randomized study, 35 men were pretreated for 3 months with finasteride or placebo before transurethral resection of the prostate. The study was inconclusive because it did not show any benefit in terms of reducing perioperative bleeding during or after the resection but there is a need for a large, prospective, randomized study.
