[Vesico-umbilical fistula. Occurrence in an adult].

Vesicoumbilical fistula in the adult male basically results from repermeability of the urachus obliterated by an uncompensated vesicoprostatic obstruction. The passage of urine through the umbilicus is practically pathognomonic and the definitive diagnosis is made by IVP and cystourethrography. It is a relatively benign pathology with a good prognosis following surgical treatment. Herein we report a case of vesicoumbilical fistula in an adult male with a previous history of prostatic syndrome and chronic urinary retention, resulting in repermeability of the urachus.
