The incidence of impotence following transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH) was investigated, as well as its correlation with the localization of peroperative capsular perforations and the amount of prostate tissue resected. Patients underwent an interview questioning their potency before and after TURP. For each patient, the TURP technique was reviewed: the localization of eventual capsular perforations was noted and the amount of tissue resected was recorded. Of the 100 patients assessed, 83 were anamnestically potent prior to TURP. Of these, 27 (##%) reported complete loss of erections after operation. Peroperative capsular perforations adjacent to the neurovascular bundles and small-size adenomas correlated significantly with postoperative impotence. The results suggest that capsular perforations adjacent to the neurovascular bundles may be a cause of impotence after TURP, and that patients with small-size adenomas bear a higher risk of post-TURP erectile dysfunction.
我们对经尿道前列腺电切术（TURP）治疗良性前列腺增生（BPH）后阳痿的发生率及其与术中包膜穿孔部位和切除前列腺组织量的相关性进行了研究。对患者进行访谈，询问他们在TURP前后的性功能。对每位患者的TURP技术进行回顾：记录最终包膜穿孔的部位，并记录切除组织的量。在评估的100例患者中，83例在TURP术前性功能正常。其中，27例（##%）术后报告完全丧失勃起功能。术中与神经血管束相邻的包膜穿孔及小腺瘤与术后阳痿显著相关。结果表明，与神经血管束相邻的包膜穿孔可能是TURP术后阳痿的一个原因，小腺瘤患者发生TURP术后勃起功能障碍的风险更高。
