[A case of sigmoid-vesical fistula complicating diverticulitis of the colon]

The clinical course of sigmoidvesical fistula due to rupture of colonic diverticulitis is described. The patient, a 72-year-old-man, had chief complaints of cloudy urine, pneumaturia and fecaluria. The fistula was diagnosed by cystoscopy. In this case, primary resection of the sigmoid colon and wedge resection of the bladder including fistula were performed, and the sigmoidvesical fistula was completely cured. Statistical analysis was made on 43 cases of colovesical fistula due to diverticulitis in Japan including our own case.
