title: [Semi-radical transurethral resection of the prostate for small benign prostatic hyperplasia].
abstract: The conventional method of transurethral resection of the prostate (TUR-P) is often not beneficial for small benign prostatic hyperplasia (BPH) because of a high frequency of postoperative bladder neck contracture (BNC). Herein, we examined the usefulness of semi-radical transurethral resection of the prostate (semi-radical TUR-P) from the view points of improvement of peak flow rate, the frequency of postoperative BNC and incidental carcinoma of the prostate in 79 cases of small BPH (group A) and 101 cases (group B) of large BPH in which less than 10 g for more than 10 g of the internal glands was resected, respectively. The bladder neck was resected carefully to avoid over resection which may cause BNC in small BPH cases. Satisfactory results were obtained in both groups, that is, the improvement of the peak flow rate from 7.03 +/- 3.79 ml/sec to 13.9 +/- 7.32ml/sec and from 4.96 +/- 2.88 ml/sec to 15.2 +/- 8.30 ml/sec, and the frequency of BNC were 2.53% (2/79) and 1.98% (2/101) in groups A and B, respectively. The frequency of incidental carcinoma of the prostate were 15.2% (12/79) and 17.8% (18/101) in groups A and B. We conclude that semi-radical TUR-P is a favorable maneuver for small BPH because of satisfactory improvement in peak flow rate with low frequency of postoperative BNC and its superiority in screening test for incidental carcinoma of the prostate.
