[Bifid ureter with blind-ending branch, a diagnosis by excretory urography (author's transl)].

Bifid ureter with blind-ending branch must fulfill the criterias of Culp. Retardation of ureter growth or degeneration of a ureteral segment after fusion with the metanephrogenic tissue are to be considered as the cause for this anomaly. Infrequently other, preferably congenital lesions of the kidneys or other organ systems are combined. The bifid ureter with blind-ending branch can be a casual finding. But it may cause symptoms which make resection necessary. The diagnosis is possible by excretory urography. Two cases are added to the known 66 patients in the literature.
