[Pyeloduodenal fistula. Apropos of a new case].

A pyelo duodenal fistula is rarely observed although anatomical relations between the high urinary tract and digestive tractus are closed. The authors report here a new observation of pyelo-duodenal fistula and make correlations with the 73 observations published in mondial literature. Spontaneous fistulas from urinary etiology are the most frequent. This urinary pathology is revealed by general and digestive signs. Duodenal fistula could usually be stiched up. Renal destruction require nephrectomy.
