Single vaginal ectopic ureter via Gartner's duct cyst spontaneously perforating into the bladder.

We report on a girl with a rare variant of single vaginal ectopic ureter via Gartner's duct cyst, which ruptured spontaneously into the bladder leading to aggravation of urinary incontinence. The patient also had a megalovagina, and a fistula between the distal urethra and vagina. She became continent after removal of a dysplastic kidney, unroofing of the cyst and closure of the fistulas.
