Abnormal DMSA renal scan findings and associated factors in older children with vesicoureteral reflux

Complete Remission of Renal Scarring in Follow-Up DMSA Renal Scintigraphy After Urinary Tract Infection

“…This result was theoretically acceptable because cases with severe clinical symptoms usually exhibit abnormal DMSA renal scintigraphy findings and VUR. [8][9][10]36 Dimercaptosuccinic acid renal scintigraphy is used to visualize tracer uptake in renal tubular cells, as it reflects the function of proximal tubular cell membrane transport and the amount of renal blood flow. 11,13,41 A decreased tracer uptake indicated that proximal tubular cell function and the amount of renal blood flow were weakly preserved.…”

“…Abnormal findings, such as renal scarring, on chronic phase DMSA renal scintigraphy, were defined and classified into the following categories based on the severity of image findings: grade 0; normal tracer uptake and renal contour; grade 1, decrease in tracer uptake without diminishing renal cortical contour (Figure 1); grade 2, defect of cortical contour-decrease in tracer uptake with diminishing renal cortical contour (Figure 2); and grade 3, renal atrophy (Figures 3 and 4). 15,18,19,[21][22][23][24][31][32][33][34][35][36] Grade 0 was diagnosed as absence of renal scarring on DMSA renal scintigraphy, and grades 1 to 3 were diagnosed as presence of renal scarring. 3-month-old male patient with decreased renal uptake in the first chronic phase DMSA renal scintigraphy, which diminished in the second chronic phase DMSA.…”
