[Clinical results and problems of anti-androgen therapy of benign prostatic hypertrophy]

We evaluated the effect of anti-androgen therapy for benign prostatic hypertrophy. Patients showed a significant reduction in the prostatic weight measured by means of transrectal ultrasonography after 3 to 4 months of treatment. However, there were no patients who showed any symptomatic improvement despite a reduction in the prostatic weight. They had prostatic stones more frequently than the group who showed symptomatic improvement properly. We summarized some problems of anti-androgen therapy for benign prostatic hypertrophy.
