Bicornuate and unicornuate uterus associated with unilateral renal aplasia and abnormal solitary kidneys: report of 3 cases.

We present 3 cases of a genital abnormality associated with unilateral renal aplasia in which the single kidney was abnormal. Renal aplasia associated with unicornuate uterus or uterus didelphia is rare but it has been reported previously. However, except for vesicoureteral reflux the single kidney usually is normal. Modern methods of evaluating renal function and urodynamics will be helpful when abnormal kidneys are found and will avoid unnecessary surgery. It is mandatory to suspect abnormalities of the urinary tract when genital maldevelopment is encountered and vice versa.
