Abstract

Objectives: To asses the value of urinary oxygen pressure for evaluation of renal graft
outcome.
Material and Methods : In this prospective study we evaluated the oxygen pressure of
urine samples obtained from urether (Puuo2)and bladder (pbuo2) as a predictor of graft
function and outcome in 30 patients whom underwent kidney transplantation.
Results: There was statistically significant relationship between puuo2 and pbuo2 and
occurrence of acute tubular necrosis (p=0.001). In addition, there was statistically
significant relationship between systemic blood pressure and cold ischemic time and
occurrence of acute tubular necrosis. Acute tubular necrosis was higher in patients with
systolic blood pressure less than 130 mmhg (p= 0.021).
Conclusion: This study showed that puuo2 and pbuo2 of recipients is a noninvasive and
sensitive test for determination of graft outcome. (Rawal Med J 2007;32:67-69)
