Description

Transurethral resection of prostate (TURP) is a standard surgical option for treatment of benign prostatic hyperplasia (BPH). However, TURP might not be sufficient for patients with relatively small prostatic hyperplasia. Therefore, to determine sufficient therapeutic effect on prostate volume, a series of patients treated with TURP in our hospital from January 2002 to December 2006 were included in this study. 138 patients treated with TURP were evaluated utilizing the IPSS and QOL index and maximal urine flow rate (Qmax). 45 out of 138 cases were evaluated with a uroflowmeter. Patients were classified into two groups according to prostate volume (small prostate group = prostate volume < 30 ml; large prostate group = prostate volume ≥ 30 ml). There was a significant difference in therapeutic efficacy between the two groups. The large prostate group showed significant differences regarding all seven categories of the IPSS and QOL index. However, the small prostate group showed a significant difference in only one category of IPSS and QOL index. Comparison of the improvement QOL index level of both groups indicated that the large prostate group showed a significant improvement level. From the results of this study, the IPSS and QOL index and Qmax are related to prostate volume.
