Glomerular filtration rate measured by Tc-99m-DTPA renal dynamic imaging is significantly lower than that estimated by the CKD-EPI equation in horseshoe kidney patients

摘要

Aim: Gate's glomerular filtration rate (gGFR) measured by Tc-99m-DTPA renal dynamic imaging and estimated GFR (eGFR) estimated by the Chronic-Kidney Disease Epidemiology Collaboration (CKD-EPI) equation are two indexes used to evaluate renal function. However, little is known about whether gGFR can be used to accurately assess renal function in horseshoe kidney (HSK) patients with renal fusion anomalies.
