Objective:To assess the diagnosis and treatment of enterovesical fistula.Methods:The clinical data of 6 cases(5 men and 1 women;mean age)of enterovesical fistula were retrospectively analyzed.The etiology of fistula was intestinal malignancy in 4 cases

intestinal diverticulitis 2.The clinical features included fecaluria、recurrent urinary tract infection(UTI)and pneumaturia.Five patients(4/6)had a definite diagnosis by CT;2(2/6)by cystoscopy and 1(1/3)

by cystography.Among the 6 patients undergoing surgical intervention

resection of the involved bowl with one stage anastomosis and partial cystectomy was performed in 2;resection of the bowl with one stage anastomosis and repair of the fistulain 1;one—stage transverse colostomy and two stage radical colectomy with partial cystectomy in 2 and palliative proximal colostomy in 1.Results:One patient with palliative surgery died of tumor metastasis after operation 5 months.Five patients undergoing surgery had a better survival with no complication.Conclusions:The major cause of enterovesical fistula is intestinal malignancy.Recurent UTI and fecaluria are the most common symptoms.CT three-dimensional reconstruction is the prefered adjunctive examinations.Surgical intervention is the major therapeutic choice.
