[Urologic complications of diverticulosis of the colon].

In this paper the complications of colonic diverticulosis are reported, on the basis of two clinical cases personally observed. In the first case, a 68 year-old man, the typical symptomatology with pneumaturia, cloudy urine and watery diarrhea suggested a uro-colonic fistula, therefore a fistula between sigma and bladder, caused by a perforate diverticulum, has been diagnosed by means of cystography and barium enema. In the second case, a 64 year-old woman, the irritative symptomatology, hematuria and endoscopic picture suggested a vesical neoplasia. An accurate examination with abdominal TAC and barium enema, showed a perforate diverticulum between uterus and bladder, without affecting the bladder lumen. The surgical treatment required, in both cases, a left hemicolectomy, a minimal bladder resection in the first case, and a greater one in the second case. During the discussion, the main etiopathogenetic causes of uro-colonic fistulae together with the variants in the onset symptomatology, have been stressed.
