Usefulness of 99mTc Dimercaptosuccinic acid scans after the first episode of urinary tract infection in children admitted to the Lady Ridgeway Hospital for Children, Sri Lanka.

99mTc-DMSA scan is the best investigation to assess renal scarring after urinary tract infection (UTI) in children. The aim of this study was to describe the findings of DMSA scans done six months after the first UTI. A descriptive cross-sectional study was done among 110 boys and 80 girls selected by systematic sampling. Urine culture was positive in 164 (86.3%) children. There was no statistically significant association between the DMSA scan result and gender, family history of UTI (p=1.00), family history of vesico-ureteric reflux (p=1.00), febrile UTI (p=0.134) and positive urine culture (p=1.00).In 93.7% of children DMSA scan was negative. Hence routinely recommending DMSA scans following UTI must be reconsidered.
