ABSTRACT
PURPOSE: We prospectively studied the effect of finasteride on chronic hematuria associated with benign prostatic hyperplasia. MATERIALS AND METHODS: We prospectively evaluated 57 patients with chronic intermittent hematuria who were randomized to a finasteride treated or a control arm. RESULTS: In the untreated control group hematuria recurred in 17 patients (63%) within a year but in only 4 (14%) in the finasteride group, which was a statistically significant difference (p <0.05). Surgery was required for bleeding in 7 controls (26%), while no patient on finasteride required surgery. CONCLUSIONS: Hematuria secondary to prostatic bleeding may be significant if not treated. Finasteride appears to be effective for suppressing hematuria caused by benign prostatic hyperplasia and should be considered as treatment.
