Renal dysplasia with a single vaginal ectopic ureter: the role of computerized tomography.

Renal dysplasia with a single vaginal ectopic ureter is relatively common in Japan. We report 2 cases in which delayed enhanced computerized tomography (1.5 hours later) contributed in detecting a dysplastic kidney that had been nonfunctioning on excretory urography. We believe that computerized tomography is a useful technique for the diagnosis of renal dysplasia with a single vaginal ectopic ureter.
