[Incomplete duplication of the urethra with intra-rectal opening of the posterior chanel (author's transl)].

We have described two cases of urethro-rectal fistulae: outstanding by their absence of anorectal abnormality. This type of malformation must be separated from the fistula observed in imperforated anus. We consider it as an incomplete duplication of the urethra; the posterior part ending in the rectum: this is a very rare abnormality. The treatment involves a separation of the posterior urethra from the rectum to bring it up to the preneum then continue as in an hypospadias usig the Duplay and Leveuf (Cecil) techniques. Seemingly normal urethra is hypoplastic in part or entirely.
