[Double uterus malformation with unilateral kidney agenesis].

When double uterus is observed, absence of one kidney is common. These rare congenital anomalies are known in literature. In the years 1980-1984 we observed four cases. Symptoms, diagnosis and therapy are described. Preoperative diagnosis is now much better by ultrasonography. Nevertheless operative procedure has to be adapted to the real anatomic situation at first within the intervention. In one case a second operation was necessary because of a recurrence. This case is described in detail.
