appendicovesical fistula: a rare complication of appendicitis

appendicovesical fistula is an uncommon type of enterovesical fistula and a rare complication of unrecognized appendicitis. appendicovesical fistula often presents with recurrent or persistent urinary tract infection, especially in men. the commonest causes are appendicitis, cecal diverticulitis, and cystadenocarcinoma or carcinoid tumors of appendix. approximately 114 cases have been reported previously in the literature, the vast majority in young male patients. our special case joins the other cases which have already been described in the international literature. this case is a middle-aged man and is the first who has large and multiple fecaliths. we reviewed other cases and contributed an additional one with hope that increased awareness of this entity may facilitate the correct diagnosis and avoid inappropriate management.
