Ureteral reflux from ileal conduit.

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 (less than or equal to 12 cm H2O) was observed in about 50%. No correlation between the conduit pressure and the occurrence of ureteral reflux was found.
