[Rectosigmoid reservoirs (pouch)].

A low pressure and high capacity rectosigmoid reservoir for urine is formed without the need for colostomy, augmentation or extensive bowel surgery. Reservoir is created by antimesenterial detubularization of the rectosigmoid and subsequent suturing. The authors describe the operation technique and analyses the results in 20 patients who were followed up 1-25 (average 14) months after operation. All patients are continent during the day time and at night. Two patients had at the sites of implantation ureteral stricture, which in one necessitated reoperation and undiversion and in the other endoscopic dilation of the stricture.
