Abstract

Objective: To compare the prostate volume and post-void residual urine volume between 2 treatment methods in men with benign prostatic hyperplasia (BPH), α1‐blocker alone and a combination α1‐blocker plus 5α-RI. Subject and method: This was a multicentre, randomised, open‐label, parallel‐group study in 100 men with BPH. Patients were randomised to α1‐blocker plus 5 α-RI (50 patients) or α1‐blocker alone (50) and followed for 6 months. Result: The prostate volume of patients treated by avodart plus doxazosin fell off markedly after 3 months and 6 months (18.6% and 26.3%, p<0.05), while that of doxazosin alone group witnessed a slight increase. The post-void residual of urine of patient in both categories experienced the same trends over the period of 6 months. Particularly, there was a significant drop in that of combined therapy group, from 17.39 ± 21.79 ml to 24 ± 13.96ml and 4.68 ± 7.36ml after 3 months and 6 months, respectively (p<0.01). However, the 6 months brought a considerable elevation to the remaining category. Conclusion: The combined therapy with α1‐blocker plus 5α-RI resulted in rapid and sustained improvements in men with moderate to severe BPH symptoms at risk of progression with significantly greater symptom and a significantly reduced risk of BPH progression compared with α1‐blocker alone.
