Partial vaginal agenesis with a urinary-vaginal fistula.

A patient with partial vaginal agenesis and a urinary-vaginal fistula is presented together with a review of the 12 cases reported previously. This unusual anomaly presents with cyclically recurrent hematuria; hypothetically, it results from failure of formation or canalization of the primitive vaginal plate together with partial persistence of the urogenital sinus. Surgical correction, ideally performed after puberty, requires resection of the fistula and mobilization of the apical vaginal segment for its anastomosis to the inferior vaginal pouch.
