Objectives: After studying the article entitled, “Reliability of Sonography for the Prediction of Vesicoureteral Reflux in Children With Mild Hydronephrosis,” you will be able to:
Identify the relationship between prenatal hydronephrosis (HN) and vesicoureteral reflux (VUR) in children with mild HN
Determine when to use sonography for the prediction of VUR in children
Recognize the limitations of sonography in the diagnosis of VUR in children
Antenatal HN accounts for what percentage of genitourinary anomalies detected by prenatal sonography? 20% 30% 50% 70%
In this study, why was the renal pelvis diameter (RPD) measured both before and after micturition? To avoid the effect of bladder distention To rule out post-void residual urine To differentiate pre-void and post-void bladder volume To compare bladder wall thickness
According to the results of this study, sonography is a reliable method for the predicting which of the following? Low-grade VUR Medium-grade VUR High-grade VUR All grades of VUR
In children with mild HN, voiding cystourethrography (VCUG) was performed if: RPD is >25mm Persistent in two or more postnatal sonograms Internal echoes are detected on sonogram It is bilateral
According to existing studies, what was considered the only reliable method for evaluating VUR in children with postnatal HN? Sonography Cystoscopy Pyelography Cystography
