ABSTRACT
Objective To investigate the effect of asymptomatic hyperuricemia after renal transplantation on renal function of the grafts.Methods The follow-up data were retrospectively collected and analyzed in 144 patients with renal transplantation from January 2010 to March 2015.The patients were classified into three groups according to the level of serum uric acid (SUA):group A (normal group),group B (asymptomatic hyperuricernia with average SUA less than or equal to 360 μmol/L after treatment),and group C (asymptomatic hyperuricemia with average SUA greater than 360μmol/L after treatment).The renal function indexes such as serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) were compared among three groups from 12 to 48 months after transplantation.Results The SCr and eGFR showed no significant difference between group A and group B at 12th month (P＞0.05),but ther are superior than Group Ⅲ (P＜0.05).Conclusion After renal transplantation,asymptomatic hyperuricemia can lead to impaired renal function,and there are no significant differences in renal function between renal transplant recipients with normal SUA levels after treatment and those without hyperuricemia.
