Detection of ectopic ureteral insertion to vagina with hypoplastic ectopic kidney by three-dimensional computed tomography.
A 3-year-old girl presented with constant urinary dribbling. 3D-CT imaging clearly demonstrated the left hypoplastic ectopic kidney and vaginal insertion of a single ureter. Left kidney contributed 1.6% of total renal function. She was diagnosed as having a left hypoplastic ectopic kidney with ectopic ureter draining into the vagina, and laparoscopic nephrouretectomy was performed. Although some imaging modalities rarely show ectopic insertion of the ureter, 3D-CT imaging can accurately depict both hypoplastic ectopic kidney and ectopic ureteral insertion, and improve the visualization of these structures as well as delineating the relationship among the ureter, bladder and vagina.
