Endoscopic findings in hemodialysis patients upon workup for kidney transplantation.

Upper gastrointestinal (GI) abnormality is believed to be higher in patients with end-stage renal disease (ESRD) which can make a big trouble for whom undergo kidney transplant. We conducted this study to assess upper GI findings of patients with ESRD. In the present retrospective study we recorded upper GI endoscopy results in hemodialysis patients who were candidate for renal transplantation during a 10-year period. We reviewed files of 1256 patients with a mean age of 37.6 ± 13.4 years. Half of patients (50.6%) had an abnormal endoscopy. Two most common abnormalities were mild gastritis (35.6%) and gastro-esophageal reflux disease (16.7%). GI ulcers were observed in 11% of patients. Duodenal ulcer was the most common ulcer which was seen in 6.8% of patients. Helicobacter pylori was positive in 32.9% of patients and correlated with GI lesions (P = 0.000, r = 0.371). Longer dialysis duration and older patients revealed more upper GI abnormality (P = 0 .032, <0.001). As long as more than half of our patients have at least one upper GI involvement, we recommended that endoscopy must be done as a pretransplantation evaluation for patients without symptoms who have risk factors for ulcers.
