Abstract
We aimed to report a healed renal parenchymal defect after 6 years in a 9-year-old girl who was being followed for recurrent urinary tract infection (UTI). The first UTI was at the age of two. She was being followed with ultrasonography, urine analysis and urine culture since the first UTI. Technetium-99m dimercaptosuccinic acid (DMSA) scintigraphy was repeated four times up to the present day. She had a renal parenchymal defect reported as parenchymal scarring, which healed 6 years after the first DMSA scintigraphy. Conflict of interest:None declared.
Highlights
We aimed to report a healed renal parenchymal defect after 6 years in a 9-year-old girl who was being followed for recurrent urinary tract infection (UTI)
It is estimated that 60–65% of patients with febrile UTI may have acute pyelonephritis (APN) [2]
UTI can affect the renal parenchyma and the children with renal parenchymal involvement are at risk of permanent renal damage that may lead to renal scarring, hypertension, complications during pregnancy and renal failure [3]
Summary
We aimed to report a healed renal parenchymal defect after 6 years in a 9-year-old girl who was being followed for recurrent urinary tract infection (UTI). A hypoactive area in the superior-lateral of the right kidney was reported (Figure 1) and repeating the scintigraphy after 6 months was recommended to differentiate acute pyelonephritis from renal scarring. The differential functions were 49 % for the right kidney and 51 % for the left kidney Two years after this third DMSA scan, the patient underwent bilateral subureteric injection for persistent vesicoureteral reflux. Evaluation of the therapy outcome for bilateral subureteric injection, she underwent direct vesicoureteral scintigraphy and vesicoureteral reflux was demonstrated in the right kidney She could not be followed regularly for the four years and she was again referred to our clinic to evaluate the status of right kidney 4 years after the third DMSA scan at the age of 9. The differential functions were 39 % for the right kidney and 61 % for the left kidney
