Abstract：Objective: To investigate the clinical significance of 99mTc-DTPA renal dynamic imaging in evaluating renal function as intravenous pyelography(IVP) detection failed. Methods: Sixty-six abnormal kidneys in 64 patients which IVP detection failed were accepted for 99mTc-DTPA renal dynamic imaging. Results: 99mTc-DTPA renal dynamic imaging demonstrated that all the IVP detection failed kidneys had poor function and nonfunction, detailed as: grade 0 in 2 cases, grade I in 3 cases, grade II in 7 cases, grade III in 36 cases, grade IV in 18 cases. And the average GFR was 53.7ml/min, 35.8ml/min, 21.1ml/min, 12.8ml/min and 7.8ml/min respectively. Twenty cases which 99mTc-DTPA renal dynamic imaging showed normal function or function slightly damaged on the contralateral kidney, the affected kidney received nephrectomy, others accepted expectant treatments and mostly with good recovery. Conclusion: 99mTc-DTPA renal dynamic imaging is an ideal method to assess preoperative renal function especially the single renal function in IVP detection failed patients. It is a simple, noninvasive, with high-sensitivity and repeatability.
