Abstract

Objective: To discuss the clinical application value of renal dynamic imaging in the diagnosis of patients with congenital renal dysplasia. Methods: Twelve cases with congenital renal dysplasia underwent 99mTc-DTPA renal dynamic imaging and abdominal ultrasound examination, 11 cases among them underwent abdominal enhanced CT scan, and 8 cases among them underwent intravenous pyelography(IVP). Results: Seven cases were diagnosed by 99mTc-DTPA renal dynamic imaging(58.3%, 7/12). The detection sensitivity by DTPA imaging was equivalent to enhanced CT scan(χ2＝1.5, P>0.05), and was superior to ultrasound(χ2＝4.4, P<0.05). Only 2 cases among 8 cases underwent IVP. The average values of GFR in the affected side kidney were obviously lower than normal side kidney(t=10.2, P<0.05). Conclusions: 99mTc-DTPA renal dynamic imaging is an effective tool to diagnose renal dysplasia and evaluate kidney function at the same time.
