title: The Pyrah technique for ileal loop diversion: experience with 100 cases.
abstract: One hundred patients underwent ileal loop diversion using the Pyrah technique between 1959 and 1975. Sixty-seven were performed because of benign urinary tract lesions and 33 were performed as part of planned treatment of various malignant conditions. Neurogenic bladder dysfunction accounted for 56 of these diversions. There were 67 early and 69 late complications. Patients having preoperative irradiation therapy had a much higher incidence of complications. An alarming 19 per cent demonstrated progressive deterioration of the upper tracts following diversion. It is noteworthy that this rate of upper tract deterioration compares favorably with that reported in several other series. Early mortality was 6 per cent, and death occurred four times more often in patients with malignant conditions.
