Urethral stenosis in children is rare. Between 1961 and 1993, only five specific retrospective studies were published. Between January 1987 and December 1992, thirty-three children, i.e. thirty boys and three girls, were observed in our institution for urethral stenosis. Their ages ranged from two and half months to seventeen years. Etiology was congenital in six, traumatic in two, inflammatory in two and iatrogenic in thirteen patients. In additions, ten stenoses were consecutive with hypospadias repair. Seventeen patients underwent first-line endoscopic internal urethrotomy. Success rate was ninety-one percent. Two patients underwent a successful second similar procedure. Repeating this procedure more than twice and second-line urethrotomy doesn't improve success rate. It appeared that internal urethrotomy proved to be more effective in short and recent stenosis. Fourteen patients underwent urethroplasty by using various techniques, of whom only five first-line urethroplasty. Its indication in case of multioperated or complicated stenoses may explain the poor global success rate of about fifty percent.
儿童尿道狭窄较为罕见。1961年至1993年间，仅发表了五项具体的回顾性研究。1987年1月至1992年12月期间，我院共观察到33例尿道狭窄患儿，其中30例为男孩，3例为女孩。他们的年龄从两个月半到17岁不等。病因方面，6例为先天性，2例为创伤性，2例为炎症性，13例为医源性。此外，10例狭窄与尿道下裂修复术相关。17例患者接受了一线内镜下尿道内切开术，成功率为91%。2例患者成功接受了第二次类似手术。重复该手术两次以上及二线尿道切开术并不能提高成功率。似乎尿道内切开术在短时间内和近期狭窄中更为有效。14例患者采用各种技术进行了尿道成形术，其中仅5例为一线尿道成形术。其在多次手术或复杂狭窄病例中的应用可能解释了总体成功率约为50%的不佳情况。
