ABSTRACT
We present a case of vaginal ectopic ureter with ipsilateral partial duplication of the upper ureter (Y-type ureter), ipsilateral hypoplastic pelvic kidney and bicornuate uterus in a 20-year-old woman, who presented with mild urinary incontinence since infancy. Ultrasonography, computed tomography and intravenous pyelography examination showed a left kidney with no evidence of a right kidney. Cystourethroscopy showed absence of the right hemitrigone. Magnetic resonance (MR) urography demonstrated the presence of a bicornuate uterus, an ectopic dysplastic right kidney in the pelvic cavity, and a right ureter that terminated in the fornix vaginae. The patient underwent right nephroureterectomy, and urinary continence was restored completely. Although congenital malformations of the urinary tract are frequently associated with genital tract abnormalities, this is, to the best of our knowledge, the first report of the coexistence of these anomalies in an individual. Our report also highlights the importance of MR urography in the diagnosis of such rare and complex anomalies.
