99Tcm-diethylenetriaminepenta hydroxamic acid renal dynamic imaging to evaluate split renal GFR of unilateral renal function failure patient

Objective To explore the use of evaluating split glomerular flow rate (GFR) in patients with unilateral renal function failure by 99Tcm-diethylenetrlaminepenta hydroxamic acid renal dynamic imaging. Methods Split GFR of 82 cases with unilateral renal function failure was evaluated by 99Tcm-DTPA renal dynamic imaging, and was correlated with serum creatinine (SCr). Beside, causes of renal function failure were analyzed. Results Split GFR were negatively correlated with SCr(r=-0.643, P<0.001). In the cases with unilateral renal function failure, renal calculi and urinary transitional cell carcinoma were mainly causes to injure the renal function. Conclusion It is very important of evaluating split GFR in patients with unilateral renal function failure by 99Tcm-DTPA renal dynamic imaging to treat early and reserve renal function.
