While VCUG is considered the standard technique for diagnosis, controversies exist on application of other modalities for investigating renal function. In this study we aim to introduce "foot print" sign; an acute-phase sign observed in VCUG that could add information regarding patient's renal function. MATERIAL AND METHODS In this retrospective study, medical records of 210 patients diagnosed with VUR were reviewed. Patients with either foot print sign in their VCUG or high grade VUR (grade IV, V) were included in the study. Renal function was compared between patients with or without foot print sign, by the aid of recorded Relative DMSA uptake percentages. RESULTS Fifty-nine patients with a mean age of 11.4 months were included. Among these patient, eleven renal units with foot print sign were recorded. Analysis of patients' records demonstrated that rela- tive DMSA uptake percentage was significantly lower (p<0.001) in renal units with foot print sign (12.93 %) compared to those without this sign (37.91 %). Ten out of thirteen patients with relative DMSA uptake of less than 20 percent had footprint sign. Sensitivity, specificity, PPV, and NPV of the foot print sign for detection of refluxing units with relative DMSA uptake less than 20 % was 76.9 %, 99.7 %, 90.9 % and 93.6 % respectively. CONCLUSIONS Footprint sign could be an indicator of poor renal function, even in patients with moderate VUR; therefore, its observation in VCUG suggests further functional imaging including DMSAscintigraphy. 09:01–09:04 S5-4 (PP) ★ DID OUR CURRENT INITIAL TREATMENT PRACTICE CHANGE AFTER EAU/ESPU VESICOURETERAL REFLUX RISK GROUPING?
