[Gastrointestinal fistulae of the upper urinary tract (author's transl)].

A case of ureteroduodenal fistula is presented. The subject of gastrointestinal fistulae of the upper urinary tract is reviewed. These fistulae usually exhibit a sparse atypical symptomatology in contrast to fistulae of the lower urinary tract. Retrograde ureteropyelography proves to be the most helpful diagnostic tool. Removal of the involved kidney has been found to be necessary in most of the published cases.
