Abstract
In 14 patients with ileal conduit urinary diversion the frequency of ureteral reflux was studied and the intraluminal conduit pressure was registered. Reflux was found in 20 (67%) of the 30 ureters (2 patients with 3 ureters each). The frequency was approximately the same in the erect and supine body positions. Low pressure reflux (≤12 cm H2O) was observed in about 50%. No correlation between the conduit pressure and the occurrence of ureteral reflux was found.
