3. Fig GU 20-1 Complete duplication with ureteral obstruction. (A) Excretory urogram demonstrates dilatation and lateral displacement of the right ureter. Ureteral duplication was not suspected. (B) A delayed film after a voiding cystogram demonstrates contrast material filling a dilated and tortuous ureter to the upper segment. This ureter, which was not seen on the excretory urogram , has laterally displaced the ureter to the lower segment. 20

4. Fig GU 20-2 Ileal conduit stenosis. Drainage film from an ileal loopogram shows bilateral hydronephrosis, right lower pole parenchymal scarring (arrow), and failure of the conduit to empty. 21

5. Fig GU 20-3 Vesicoureteral reflux. Voiding cystogram in a young girl shows bilateral reflux with gross dilatation of the upper tracts.

6. Fig GU 20-4 Prune belly syndrome. Pronounced bulging of the flanks (open arrows). The patient had multiple genitourinary anomalies, including hydronephrosis of the right collecting system (small arrow).
