Abstract： @@ 先天性肾积水是小儿泌尿外科的常见疾患,产前超声筛查中胎儿的发生率约为1/500～1/100[1].但是,梗阻性尿路病变最终仅发生于这些被筛查出的患儿中的一部分,而其中许多患儿日后并无进行性肾功能损害,不需要外科治疗.小儿肾积水的原因多为先天性肾盂输尿管连接部狭窄导致的梗阻,其次是输尿管远端梗阻.这些梗阻通常是慢性的、部分性的.在临床工作中,小儿肾积水就诊患者基于年龄可大致分为两大类:前者为产前和(或)产后超声检查发现肾积水,其中仅25%～50%需要外科治疗,而其余患儿长期随访肾功能及积水情况保持稳定或改善缓解[2];后者往往因腹痛、血尿或尿路感染等症状而发现,多需要手术治疗.
