The aim of this study was to investigate the normal values of glomerular 
filtration rate (GFR) by technetium-99m diaethylene-triamine-pentaacetic acid 
((99m)Tc-DTPA) renal dynamic imaging for living kidney graft donors. In a total 
of 212 candidate donors, GFR was examined using (99m)Tc-DTPA renal dynamic 
imaging. Donors with GFR≥80mL/(min×1.73m(2)) and as low as with 
GFR≥70mL/(min×1.73m(2)) but a normal endogenous creatinine clearance rate (CCr) 
were quantified for living kidney donation. Differences in GFR levels based on 
sex and age were analyzed using rank correlation coefficient. Out of the 212 
candidates, 161 were finally selected as kidney graft donors. The double kidney 
total GFR between the male and female donor groups, the GFR levels among 
differently-aged donor groups, and the GFR levels between the elderly (>55 
years) and young- and middle-aged (≤55 years) donor groups did not show any 
significant difference (P>0.05). After kidney donation, renal function measured 
by blood urea nitrogen (BUN) and serum creatinine of all donors returned to 
normal within one week, and no serious complications were noticed. In 
conclusion, renal dynamic imaging by (99m)Tc-DTPA had a good accuracy and 
repeatability in GFR evaluation for living kidney donors. Candidate donors with 
GFR between 70mL/(min×1.73m(2)) and 80mL/(min×1.73m(2)) can be selected as 
kidney donors after strict screening. In living kidney donors GFR is not 
significantly correlated with age or sex.
