[Percutaneous demonstration of ectopic megaureters].
Preoperative diagnosis of ectopic megaureter has become much simpler using percutaneous transvesical fine needle puncture of a sonographically visible retrovesical megaureter. Antegrade ureterography using watery contrast material together with indigocarmine dye was able both to demonstrate the megaureter roentgenologically and to help finding the ectopic orifice by direct vision or colposcopy in three girls.
