Duplex kidneys occur in 0.8% of the general population, many of whom are asymptomatic. Children with duplex kidneys may be prone to urinary tract infections because of vesico-ureteric reflux or obstruction. Surgical management is usually required once symptoms occur. Increasing numbers of duplex kidneys are now prenatally diagnosed by ultrasound, resulting in the development of early postnatal strategies to try and reduce morbidity.
重复肾在普通人群中的发生率为0.8%，其中许多人没有症状。患有重复肾的儿童可能因膀胱输尿管反流或梗阻而容易发生尿路感染。一旦出现症状，通常需要进行手术治疗。现在越来越多的重复肾在产前通过超声诊断出来，这促使人们制定出生后早期策略以试图降低发病率。
