Donor kidney glomerular filtration rate and post-transplant graft function.

This study aimed to estimate the relationship between the single kidney glomerular filtration rate (SKGFR) of a planned kidney transplant and the subsequent graft function and survival of living related kidney recipients (LKRs). Of 180 LKRs with the graft functioning for more than a year, 70 patients without delayed graft function (DGF) or acute rejection (AR) were selected for the study. According to SKGFR, assessed by 99mTcDTPA, the patients were allocated into Group 1, receiving kidney with SKGFR < 50 mL/min (32 patients), and Group 2, with SKGFR > 50 mL/min (38 patients). The database included donor, recipient and transplant variables. No significant difference was found between the patient and graft survival rate, creatinine clearance (CCr) and the rate of CCr change between the groups. Additional evaluation revealed no significant influence of the ratio of SKGFR and the recipient's body weight/size on patient and graft outcome. The analysis of factors of influence on patient and graft survival and function revealed the major influence of nonimmunological factors but not of SKGFR of the transplanted kidney. Our study did not confirm the influence of SKGFR on graft function and survival in the LKRs without DGF and AR but the limited number of patients must not be disregarded.
