Evaluation of ultrasound in detecting renal scar compared with DMSA in children from 2 to 10 years old in Sanandaj in 2020-2021

Background and Aim: Fibrosis and irreversible kidney damage that occur with inflammation are defined as renal parenchymal scar. Kidney scar occurs in children with pyelonephritis, and it is one of the major complications of urinary tract infection. DMSA is an excellent method to examine the renal cortex. It is also useful in making treatment decisions for these patients. This study aimed to evaluate the diagnostic value of ultrasound in detecting renal scar compared with DMSA in children from 2 to 10 years in Sanandaj in 2020-2021. Materials and Methods: This descriptive study was performed on 70 patients from 2 to 10 years old with a history of vesicoureteral reflux or urinary tract infection who had a kidney scar on the DMSA scan. These patients underwent renal ultrasound. Then ultrasound results were compared with the DMSA results of each patient. All data were entered in STATA-14, then frequencies, percentages, and standard deviations were calculated. Results: The results of this study showed that 60 percent of the subjects were female and 40 percent male. All scars were detected in all patients with DMSA scan, while only 41/4% were diagnosed by ultrasonography. Conclusion: In this study, the sensitivity of ultrasound in detecting renal scar was reported to be low. This research showed that ultrasound could not be an appropriate alternative to DMSA for detecting kidney scars in children.
