Vesico-ureteral reflux in pediatric kidney transplants: clinical relevance to graft and patient outcome.

Abstract：

:From June 1985 to December 1998, 173 pediatric renal transplants were carried out in 170 patients at our center. From this pool, 73 patients (34 males and 39 females) with a follow-up of 48 months were examined. In all patients, ureteroneocystostomy was performed according to the Lich-Grégoire procedure. All patients were treated with cyclosporin A (CsA)-based immunosuppression, including prednisone and sometimes azathioprine (AZA). Six months after transplantation, voiding cystography (VCU) was performed in all patients and reflux was classified from Grade I to Grade IV. The patients were divided into two groups: those with reflux (Group A: 25 patients) and those without (Group B: 48 patients). Grade I reflux was found in four patients, Grade II in seven patients, Grade III in seven patients, and Grade IV in seven patients. All the patients with severe reflux (Grade IV) underwent a corrective surgical procedure. Both groups were examined for immunologic and non-immunologic risk factors and no significant differences were found. Analysis of patient and graft survival rates revealed no statistical differences (NS) between Groups A and B. Mean serum creatinine (mg/dL) was 1.06 +/- 0.28 and 1.12 +/- 0.41 at 4 yr in Groups A and B, respectively (NS). Mean calculated creatinine clearance (cCrC; ml/min) was 76.74 +/- 15.92 and 77.96 +/- 15.66 in Groups A and B, respectively (NS). The analysis was further extended by considering the grade of reflux (I to IV). Again, no significant differences in the above parameters emerged between the reflux sub-groups; only in the Grade IV sub-group was a slight decrease in cCrC detected, although this difference was not statistically significant when compared with the other sub-groups. In conclusion, vesico-ureteral reflux (VUR) does not seem to negatively affect graft function. However, as all severe reflux patients (Grade IV) were surgically corrected, no conclusions can be drawn with regard to the influence of Grade IV reflux on long-term graft function.
