[Urethroperineal fistula in the left lateroposition (author's transl)].

The authors describe a case of urethroperineal fistula in the lateropostion. It is a rare malformation, with a varied symptomatology, which requires radiological investigations for its morphological and topographical study. Surgical treatment varies as a function of the site and size of the fistula. Basing their comments on the studies by STEPHENS [12], the authors try to give an embryological explanation of this affection.
