Abstract:
Objective: To investigate the clinical significance of
99mTc-DTPA renal dynamic imaging in evaluating renal function in the patients of upper urinary calculi.
Methods: The results of
99mTc-DTPA renal dynamic imaging and intravenous pyelography(IVP) in 227 patients of upper urinary stone diseases were analyzed retrospectively.
Results: Out of 261 kidneys,the functional ones detected by renal dynamic imaging were much more than those detected by IVP(
P<0.01).One hundred and twenty-four kidneys were not visualized by IVP,74.2% of which(92 kidneys) were indicated uptake of radionuclide by renal dynamic imaging with the average 24.3 ml/min glomerular filtration rate value.
Conclusions: 99mTc-DTPA renal dynamic imaging is an ideal method for evaluation of renal function especially in IVP detection failed patients.
