Insights
Ultrasound effectively detects higher grade vesicoureteric reflux (VUR) in young children. This prospective study found 52 sonographic reflux studies accurately identified grades II-IV VUR compared to traditional methods.
Area of Science:
- Pediatric Nephrology
- Diagnostic Imaging
- Urology
Background:
- Vesicoureteric reflux (VUR) is a common condition in children.
- Accurate detection of VUR is crucial for preventing kidney damage.
- Current diagnostic methods have limitations.
Purpose of the Study:
- To evaluate the efficacy of ultrasound in detecting VUR in children under two years old.
- To compare ultrasound findings with radiographic voiding cystourethrograms (VCUG).
Main Methods:
- A prospective study involving 52 sonographic reflux studies.
- Ultrasound utilized during the filling phase of a gas cystogram and micturition.
- Comparison with standard VCUG.
Main Results:
- Ultrasound successfully detected all higher grade VUR (grades II-IV).
- Gas bubbles visualized in the renal pelvis indicated reflux.
- High concordance with VCUG findings for significant VUR.
Conclusions:
- Ultrasound is a reliable imaging modality for detecting significant VUR in young children.
- This sonographic method offers a promising alternative to VCUG.
- Further research can explore its role in lower grade VUR detection.
Abstract:
A prospective study of detecting vesicoureteric reflux (VUR) by ultrasound is to be presented. In case of reflux, gas bubbles can be seen in the renal pelvis during the filling phase of a gas cystogram and during micturition, utilizing ultrasound as the imaging modality. In children under two years 52 sonographic reflux studies were performed and compared with radiographic voiding cystourethrograms (VCUG). All higher grade VUR (grades II-IV) have been detected by our method.
