Urinary tract anomalies associated with unicornuate uterus.

Abstract

We investigated the association between the various subclasses of the unicornuate uterus and urinary tract anomalies. We studied the urinary tract of 37 patients with a unicornuate uterus by urography and/or ultrasonography. Unicornuate uterus was diagnosed at laparoscopy or laparotomy. A total of 15 patients (40.5%) had urinary tract anomalies, including ectopic kidney in 4, renal agenesis in 6, double renal pelvis in 2, horseshoe kidneys in 2 and unilateral medullary sponge kidney in 1. No differences were observed in the frequency of urinary anomalies among the various subclasses of unicornuate uterus. Our results indicate the need to suspect a urinary tract anomaly, particularly of the kidney, in all women with a unicornuate uterus.
