[A bifid ureter with a blind branch. Apropos of a case]

A case of bifid ureter with a blind branch exhibiting no parenchymal connections is reported. Diagnosis was established by excretory urography. Less than twenty cases diagnosed in this way have been reported previously, the embryogenesis of the normal and bifid ureter is reviewed. Symptoms, which are inconsistently present, are described. Excision of the blind branch is required and should be accompanied with antireflux reimplantation of the normal ureter if called for.
