Congenital ureteric diverticula in children and adults – classification, radiological and clinical features

Radiological and clinical features of congenital ureteric diverticula in children and adults were analysed. To date, about 100 cases of a blind-ending branch of a bifid ureter have been reported. We present 13 clinically, radiologically and histologically evaluated cases of congenital ureteric diverticulum. We believe this anomaly is not as rare as hitherto believed and suggest the term congenital ureteric diverticulum for a blind-ending branch of a bifid ureter.
