An apparent ureteropelvic junction obstruction on the right side may herald an array of anomalous conditions for which the surgeon should be prepared. A case is presented in which ureteropelvic junction obstruction caused by accessory renal vessels was found in association with a preureteral vena cava and a vena caval duplication on the right side. The embryology of caval anomalies associated with preureteric vena cava is reviewed.
右侧明显的肾盂输尿管连接处梗阻可能预示着一系列异常情况，外科医生对此应有所准备。本文报告一例因副肾血管导致肾盂输尿管连接处梗阻的病例，该病例同时伴有右侧输尿管前腔静脉和腔静脉重复畸形。本文还对与输尿管前腔静脉相关的腔静脉异常的胚胎学进行了综述。
