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 terminates in the vaginae fornix. 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, to best our knowledge, this is the first report of the coexistence of all of these anomalies in an individual. Our report also highlights the importance of MR urography in the diagnosis of such rare and complex anomalies.

OBJECTIVE: To analyze magnetic resonance imaging (MRI) findings of Mullerian remnants in young females clinically suspected of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome in a primary amenorrhea workup. MATERIALS AND METHODS: Fifteen young females underwent multiplanar T2- and transverse T1-weighted MRI at either a 1.5T or 3.0T MR imager. Two gynecologic radiologists reached consensus decisions for the evaluation of Mullerian remnants, vagina, ovaries, and associated findings. RESULTS: All cases had bilateral uterine buds in the pelvic cavity, with unilateral cavitation in two cases. The buds had an average long-axis diameter of 2.64 +/- 0.65 cm. In all cases, bilateral buds were connected with fibrous band-like structures. In 13 cases, the band-like structures converged at the midline or a paramedian triangular soft tissue lying above the bladder dome. The lower one-third of the vagina was identified in 14 cases. Fourteen cases showed bilateral normal ovaries near the uterine buds. One unilateral pelvic kidney, one unilateral renal agenesis, one mild scoliosis, and three lumbar sacralization cases were found as associated findings. CONCLUSION: Typical Mullerian remnants in MRKH syndrome consist of bilateral uterine buds connected by the fibrous band-like structures, which converge at the midline triangular soft tissue lying above the bladder dome.
