Comparison of Imaging studies used for the Diagnosis and Follow up of Urinary Tract Infection in Children of Al - Jahra Area, Kuwait

Objective: To compare and correlate the different imaging modalities used to investigate children with urinary tract infection (UTI) in Al-Jahra area, Kuwait. Patients and Methods: One hundred children with proven urinary tract infection were included in this study. They were investigated using renal ultrasonogram (USG), 99m TcDimercaptosuccinic acid (DMSA) scintigraphy and micturating cystourethrogram (MCUG). The DMSA scanning was performed during the acute stage of infection for the localization of UTI in some patients and after six months of treatment in all patients. Results: Of all the children analysed, renal USG was abnormal in 13 (13%) children. DMSA scan was found to be abnormal in 34 (34%) children and MCUG in 27 (36.4%) children. 7 (9.4%) children had abnormal findings in all 3 modalities. 13 (38.2%) patients with abnormal DMSA scans had abnormal MCUG.13 (31.7%) patients with negative DMSA scans had abnormal MCUG findings.13(48.1%) patients with abnormal MCUG had normal DMSA Conclusion: Renal USG as a sole imaging modality for the evaluation of children with UTI is of limited value. Renal USG, MCUG and DMSA should be the minimum imaging studies for the evaluation of children with UTI.
