BACKGROUND: Although it causes low-dose radiation exposure, dimercaptosuccinic acid (DMSA) renal cortical scintigraphy is the gold standard examination method in the noninvasive diagnosis of renal scar tissue (RST). Shear wave elastography (SWE) has recently come to the fore as a technique for measuring kidney stiffness in the examination of RST. The present study aims to compare DMSA and SWE tests to evaluate whether SWE can be used instead of DMSA as a test that does not cause radiation exposure in pediatric patients.
METHODS: In this prospective study, sonographic elastography was performed on pediatric patients with DMSA images. In the SWE examination, measurements were made from each kidney's upper, middle and lower parts. DMSA and elastography data were compared for the diagnosis of RST.
RESULTS: A total of 64 patients were included in the present study. There were 68.8% female ( n = 44) and 31.2% ( n = 20) male patients. There were 45 pediatric patients [Female 30 (66.7%), male 15 (33.3%)] in group 1 (pathological group) and 19 pediatric patients [Female 14 (73.7%), male 5 (26.3%)] in the control group. When DMSA data and SWE values were compared, it was found that elastography did not show a statistically significant performance in predicting renal scarring.
CONCLUSION: In the existing literature, various studies reported different values for the diagnosis of renal stiffness using SWE. Similar to some previous studies, the present study observed no significant correlations between DMSA and SWE. Thus, DMSA preserves its major role and effectiveness as an important predictor of RST in pediatric patients.
