A retrospective cross-sectional study conducted at Mediclinic City Hospital; a teaching hospital in collaboration with Mohammad Bin Rashid University for Medicine and health sciences in Dubai, United Arab Emirates (UAE). The aim of this study is to ascertain conduction of renal radio nuclear investigations, explicitly Kidney ureter bladder ultrasound scans (KUB US), Micturating cystourethrogram (MCUG), and Dimercaptosuccinicacid (DMSA) in children following Urinary Tract Infection (UTI), based on; age, type of UTI, and recurrence. Medical records of 421 patients aged 0-16 years with UTI were retrospectively studied. Sociodemographic variables were age, gender, type of UTI, and recurrence. Results showed that the most carried out investigation was KUB US (38.2%) (n=161). In children aged between 7 months and 3 years, 15% (n=8) of them had VUR or renal scarring, while only12% (n=11) of children aged > 3 years showed abnormal MCUG or DMSA regardless of the KUB US results. Interestingly more than half (56%) (n=236) of all patients (n=421) with recurrent UTI showed abnormalities by MCUG and or DMSA, while only 12.3% (n=14) of children with atypical UTI showed abnormalities. It is concluded that VUR and renal scarring predominantly occurred in patients with recurrent UTI and atypical UTI. Thus, children presenting with recurrent UTI are recommended to undergo MCUG and DMSA after the second recurrent episode rather than waiting for the third UTI incident. This study suggests that children aged 7 months to 3 years post UTI should undergo KUB US, MCUG (if it was a recurring UTI) plus DMSA or MAG3 with post-micturition study instead. Children older than 3 years presenting with recurrent UTI are recommended to undergo DMSA (regardless of the US results) and MAG3 with post-micturition study or MCUG especially if DMSA is abnormal. Keeping in mind, evaluating risk factors like family and past medical history are crucial before conducting any investigation, this is to avoid unnecessary scans, and at the same time implement measures to reduce risks resulting from complicated UTIs.
