Studied 44 patients: renal failure, kidney stones, lupus renal functional maps with Tc99m-DTPA in the nuclear medicine department, Viet-Tiep hospital, Hai Phong, assessing glomerular filtration function of twokidney (GFR), GFR individual kidney and combined kidney radiation map analysis to evaluate the results and compare them with blood creatinine. study found 6 patients (13.63 percent) had a GFR 50 ml/p, three cases can take a side filtering (6.81 percent), 2 patients (1 percent) on the radiation map kidney can accumulate and 1 patient with a renal atrophy. Thus, results of radiation kidney function with Tc99m-DTPA can be used to evaluate the overall glomerular filtration rate and renal filter each, combining morphological surgery kidneys, ureters.
