[Triple ureter. One case. Diagnostic problem and review of the literature (author's transl)].

In the light of a case of right triple ureter in a 5 month old girl, the authors review the embryology of the ureter and describe the different types of triplication. A general review of the literature including 70 cases gives an indication of the circumstances of discovery and the contribution of radiology. The complications of complete ureteral triplication are the same but greater than those of complete duplication and are related to the ectopic position of the ureteral orifices with regard to the trigone. They are dominated by reflux and stasis in the case of high ectopia and by false incontinence (20% of cases) in low ectopia.
