Abstract
Objective. To determine the incidence and pattern of abnormal scintigraphy findings in children with UTI and VUR.
Methods. Data of 118 children who underwent micturating cystourethrography (MCU) and late Tc-99m dimercaptosuccinic
acid (DMSA) scan were evaluated. Findings were categorized under the image appearance and relative kidney uptake
(RKU) and related to the grade of VUR, sex and child’s age.
Results. MCU revealed VUR (78 unilateral and 40 bilateral) of grades I, II, III, IV and V in 2, 47, 35, 19 and 15 patients
respectively. There were 52 children with normal and 66 with abnormal DMSA finding. Scarring rate was significantly
associated with high grade VUR (p=0.0023) and male gender ( p=0.0412). Bilateral scarring was seen exclusively in children
with bilateral VUR. No significant difference was found between renal scarring and child’s age in the same gender group.
Poor kidney function was shown in 5 patients.
Conclusion. Renal scarring highly correlated with grade of VUR. A strategy to perform MCU only on patients with abnormal
DMSA finding is proposed.
