Purpose:
We investigated the association between the various subclasses of the unicornuate uterus and urinary tract anomalies.
Materials And Methods:
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.
Results:
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.
Conclusions:
Our results indicate the need to suspect a urinary tract anomaly, particularly of the kidney, in all women with a unicornuate uterus.

In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
