title: Single vaginal ectopic ureter: a case report.
abstract: The seventh case of a female subject with a single, unilateral ectopic ureter draining to the vagina is reported. The renal unit was located in the renal fossa, wheras in 3 of the 7 cases reported it was within the pelvis. Although ectopia with ureteral duplication is not an uncommon anomaly the single ectopic ureter in the female subject is the rarest form of ureteral ectopia. Use of phenazopyridine hydrochloric acid as an excertory marker was most helpful in locating the vaginal orifice.
