Abstract
We altered our routine IRC protocol by including the data obtained during failed voids adding extra imaging sequences at intervals during bladder filling and by using simple mathematical criteria to determine if VUR was present when visual imaging results were equivocal We then retrospectively compared the VUR detection rates using the standard and modified techniquesWe assessed 707 renal units in 356 children over 3 years We identified 91 cases of VUR using standard methodology and 134 47 more with the modified technique Of the extra 43 cases detected 11 were noted during failed voids ten were seen within a filling sequence and 22 were inferred because the renal pelvic activity increased during an interval between two imaging sequences while the bladder was filling Mathematical evaluation was helpful in the 39 cases where the increase in activity due to VUR was ≤6 standard deviations greater than the level of background variation in activity
