Congenital urogenital anomalies that are associated with the persistence of Gartner's duct: a review.

The embryogenesis and management of congenital urogenital anomalies that are associated with ureteric ectopia and the persistence of Gartner's duct are discussed. Ureteric ectopia with Gartner's duct cyst is caused by the failure of separation of the ureteric bud from the mesonephric duct, which leads to persistence of Gartner's duct, frequently with cystic dilation. Abnormal development of the ureter subsequently causes maldevelopment or absence of the ipsilateral kidney. The diagnosis and treatment of 2 adult women with congenital urethrovaginal fistula that was associated with unilateral single ectopic ureter, renal agenesis, and Gartner's duct anomaly are presented. Surgical repair of the urethrovaginal fistulae and removal of the Gartner's duct and cyst was performed transvaginally.
