[Sigmoid-vesical fistula as a consequence of sigmoid tumor].

Because of unusual rarity of neoplastic sigmoid-vesical fistula in young patients the case of 43 years old woman, in whom the fistula was the consequence of sigmoid adenocarcinoma infiltration of urinary bladder, was presented. The patient was treated radically by resection of the sigmoid and partial resection of the urinary bladder within healthy tissue. After operation the patient was exposed to radiotherapy, after which chemotherapy followed (6 courses of 5-day chemotherapy with fluorouracil and calcium folinate). 18 months after operation, 16 months after radiotherapy and 14 after chemotherapy patient's general condition was good and control laboratory tests did not indicate the relapse of the neoplasm.
