In an 11-year period, 49 patients developed bladder neck contracture after prostatectomy--an incidence of 0.86%. This complication was found to be more common after resection of small fibrous hyperplastic prostates. The best results for treatment of the contracture were obtained after bladder neck incision, which gave a 9% incidence of recurrence; after transurethral resection of the bladder neck contracture the recurrence rate was 46%, and after bladder neck dilatation it rose to 100%.
在11年期间，49例患者在前列腺切除术后发生膀胱颈挛缩，发生率为0.86%。发现这种并发症在切除小的纤维增生性前列腺后更为常见。膀胱颈切开术后治疗挛缩的效果最佳，复发率为9%；经尿道切除膀胱颈挛缩后复发率为46%，膀胱颈扩张术后复发率升至100%。
