膀胱颈硬化症(BNC),是经尿道前列腺切除术(TUR)的远期并发症之一。从1973年1月到1982年12月的10年中,作者共施行TUR1,630例。其中前列腺增生症1,264例,前列腺结石140例,膀胱颈硬化症27例,因其它原因而施行TUR 199例。根据以下的诊断标准:1.尿道造影显示明确的膀胱颈部狭窄;2.内窥镜检查膀胱颈部有环状狭窄;3.除外神经病原性膀胱和其它原因造成的下尿路功能障碍,4.排尿量在200ml以上而平均尿流率在5ml/秒以下时。1,630例中,16例被诊断为BNC,发生率0.98％。发病时间在TUR后8～77个月,平均44.4个月。BNC与原发疾病的关系:11例
Bladder neck sclerosis (BNC) is one of the long-term complications of transurethral resection of the prostate (TUR). From January 1973 to December 1982 for 10 years, the authors performed a total of 6,600 TURs. Among them, 1,264 cases of benign prostatic hyperplasia, 140 cases of prostatic calculi and 27 cases of bladder neck sclerosis were performed in 199 cases due to other reasons. According to the following diagnostic criteria: 1. Urethrography showed a clear bladder neck stenosis; 2. Endoscopy of the bladder neck ring-shaped stenosis; 3. Exclusion of neurogenic bladder and other causes of lower urinary tract dysfunction, 4. Urine volume in the 200ml or more while the average flow rate of urine in 5ml / sec below. Of the 1,630 patients, 16 were diagnosed with BNC and the incidence was 0.98%. The onset time after TUR 8 to 77 months, an average of 44.4 months. The relationship between BNC and primary disease: 11 cases
