Dense urethral strictures developed in 3 of 36 patients (8 per cent) following transurethral fulguration of posterior urethral valves. Common potential etiologies include the use of a loop resectoscope, large size of the valves and immediate supravesical diversion. The latter results in a "dry" urethra and the strictures that resulted may be analogous to the stenosis seen following a "dry" ureteral reimplant. Techniques to maintain flow through the urethra after resection and the avoidance of an extensive resection may be helpful in preventing urethral strictures.
36例患者中有3例（8%）在经尿道电灼后尿道瓣膜后出现致密性尿道狭窄。常见的潜在病因包括使用环形电切镜、瓣膜体积大以及即刻行膀胱上引流。后者导致尿道“干燥”，由此产生的狭窄可能类似于“干燥”输尿管再植术后出现的狭窄。切除术后保持尿道通畅的技术以及避免广泛切除可能有助于预防尿道狭窄。
