A patient with an entero-urinary fistula who underwent 5 surgical interventions before being admitted to our clinic is presented. At the admittance it was specified that it is an enterourinary fistula, but the repeated investigations showed that it is an ulceration situated on the posterior wall of the descending colon, at its junction with the sigmoid, from which two fistulas come out: one towards the urinary bladder and the other towards the left iliac fossa. After debridement of the fistulas the segmentary colectomy and immediate restoration of the transit were performed. In the immediate evolution a stercoral fistula, closing itself spontaneously, reappeared. The late examination showed normal colon and urinary system without clinical alterations.
