Percutaneous intrapelvic pressure registration in patients with ureterointestinal urinary diversion

Intrapelvic pressure registration using percutaneous needle renal pelvic puncture in 4 patients with intestinal loop diversion was done to determine whether or not there is loop-ureteral reflux under physiologic condition in loop diversion without any urinary tract obstruction. There was no pressure elevation related to reflux on pressure recording. We concluded that loop-ureteral reflux in intestinal loop diversion does not occur without obstruction.
