Congenital ureteral valves are a rare cause of ureteral obstruction. While only 17 pediatric cases have been reported in the literature, this condition should be considered in the differential diagnosis of the child with upper urinary tract obstruction. The pediatric cases are reviewed, and we present an additional case in which unilateral hydronephrosis caused by a ureteral valve was first detected by ultrasound in utero.
先天性输尿管瓣膜是输尿管梗阻的罕见原因。虽然文献中仅报道了17例儿科病例，但在诊断上尿路梗阻患儿时应考虑这种情况。本文回顾了儿科病例，并介绍了另外1例病例，其中1例因输尿管瓣膜导致的单侧肾积水在产前首次通过超声检测到。
