[Late complications of the intestine after radiotherapy of bladder carcinoma].

Immediate reactions of the intestines during or after radiotherapy of the pelvis are very common. Later complications requiring surgical intervention are seldom found. Out of 101 patients with bladder carcinomas, we observed 4 with severe irreversible intestinal changes. These had been operated and had received post-operative radiotherapy. On 3 patients a sigmoid stenosis had to be resected under the protection of a colostomy. On the fourth patient an ileovesical fistula was closed primary.
