Authors retrospectively analysed 20 cases of follow-up 99mTc-DMSA renal scans to evaluate renal function recovery after treatment in urologic disorders of infants and children. There were 20 cases with both 99mTc-DMSA renal scans prior to and after therapy in 15 patients below 9 years old. Among them, 10 patients underwent ureteroneocystostomy under the diagnosis of vesicoureteral reflux, two patients pyeloplasty because of obstructive uropathy and one was treated with antibiatics even diagnosis of UPJ stricture. We have got the quantified uptake rate of Tc-DMSA renal scan by using the regression equation as y=0.591x 2.105 (y=the quantified uptake rate, x=the sirnple uptake rate). The number of kidneys performed proper therapy were 29, and the cases with more increased radiotracer uptake rate in the follow-up 99mTc-DMSA renal scans were 20 in number as 69% in frequency. 19 cases with improved renal function on 99mTc-DMSA renal scans didnt show any significant difference related t.o aging or recovery duration after therapy. The 99mTc-DMSA renal scans were not useful to evaluate renal function recovery in infants and children, but could be good tests to assess residual renal function prior to or after treatment.
