Outcome of Kidney Transplantation Following End-Stage Renal Disease Due to Reflux Nephropathy

Background. Reflux nephropathy (RN) has an important place among the etiologies of end-stage renal disease (ESRD). In this retrospective study we sought to analyze posttransplantation complications among renal transplant recipients whose primary disease was RN. Methods. Seven hundred forty-five patients who underwent transplantation in our institution between 1983 and 2006 were included in the study. The outcomes of patients with RN (Group 1) were compared with a control group (Group 2) that consisted of age-matched, nondiabetic patients whose primary disease was chronic glomerulonephritis or unknown etiologies. Results. Group 1 consisted of 52 patients, including 20 males with a mean overall age of 25 years. Group 2 included 47 patients, including 21 males with a mean age of 27 years. There was no significant difference with regard to age, gender, donor type, donor age, modality of hemodialysis, or HI-A match between the 2 groups. Group 1 graft survival rates in the first and fifth years were 95% and 90%, respectively, and in Group 2 they were 86% and 70%, respectively (P = .302 and P = .072, respectively). There was no significant difference with respect to follow-up duration, hospital stay, or incidence of biopsy-proven or clinically suspected acute rejection episodes between the groups. During the 6-year follow-up, the incidence of biopsy-proven chronic allograft nephropathy was the same in both groups. One patient in Group 1 and 2 in Group 2 died of cardiovascular issues; 1 Group 2 patient died of infection. The frequency of urinary tract infection in Group 1 was greater than that of Group 2 (40% vs, 23%; P = NS). Conclusion. Despite the higher incidence of urinary tract infections, there was no significant difference in posttransplantation complications or patient and graft survival rates between RN patients compared with the control group.
