Our 28 patients with posterior urethral valves managed with transurethral resection have sufficient followup to evaluate the development of urethral strictures. Of these 28 patients 14 were less than 1 year old when the valves were resected and strictures developed in 7 (50 per cent). Of the 14 patients who were more than 1 year old when the valves were resected none had a stricture. Within the latter group was a subgroup of patients who were treated with early vesicostomy and later valve resection. None of these patients suffered a stricture. Our data indicate that stricture formation is high when valve resection is attempted in the neonate or small infant and can be prevented by primary vesicostomy and delayed valve resection.
我们对28例后尿道瓣膜症患者进行了经尿道切除术治疗，并有足够的随访时间来评估尿道狭窄的发生情况。在这28例患者中，14例在瓣膜切除时年龄小于1岁，其中7例（50%）出现了狭窄。在瓣膜切除时年龄大于1岁的14例患者中，无一例出现狭窄。后一组中有一部分患者早期行膀胱造瘘术，后期行瓣膜切除术。这些患者均未出现狭窄。我们的数据表明，在新生儿或小婴儿中尝试进行瓣膜切除术时，狭窄形成的发生率很高，而通过一期膀胱造瘘术和延迟瓣膜切除术可以预防狭窄的发生。
