The Efficacy of Transurethral Resection of Prostate in the Patients with Benign Prostatic Hyperplasia of 30gm or Less

Transurethral resection of the prostate(TURP) is most commonly used in relief of symptoms of the patients with benign prostatic hyperplasia. But the indications for prostatectomy are still controversial and especially those are more difficult in the cases with small prostate. To determine the efficacy of TURP in the patients with benign prostatic hyperplasia, 138 patients who underwent TURP, were reviewed retrospectively. Group I, 66 patients who's volume of prostate were under 30gm, group II, 72 patients who's volume of prostate were over 30gm by preoperative ultrasonographic measurement. And then the author made differential analysis for preoperative and postoperative symptom score and maximal urine flow.

The following results were obtained;

1) The preoperative symptom score was 10.3 for group II, 7.3 for group I, so group II showed higher score, in postoperative score group II showed 2.5 which was 76% decreased and group I showed 5.6 which was 23.4% decreased, group II showed higher decreased rate.

2) Preoperative symptom score of group II was higher than that of group I. But postoperative score was no siginificant difference. In decreased ratio, group II showed better improvement.

3) Preoperative and postoperative change in maximal urine flow in group I was increased by 44.2%, while in group II the flow change showed a 173% increased.

In conclusion, without referring to the preoperative measurement of prostatic size. TURP brought improvement of symptoms and maximal urine flow, but when the prostatic size was under 30gm, the improvement degree was minimal and significant increase in maximal urine flow was not shown. According to the results of several objective studies and patient's desire. transurethral rsection could be permitted in patients with BPH of under 30gm. But in the future, studies on the difference in progress the response to management should be done.
