Congenital unilateral renal agenesis is a relatively frequent condition at birth diagnosed mostly incidentally. Despite the excellent prognosis, unilateral renal agenesis is associated with an increased risk of other structural abnormalities, including genital malformations. The authors present two cases of asymptomatic adolescents with known congenital unilateral renal agenesis and associated genital malformations solely diagnosed during puberty—a man with Zinner syndrome and a female with Mayer-Rokitansky-Küster-Hauser syndrome.
