[Sonography of the uretero-vesical junction and the urinary bladder in children]
Insights
Sonography can visualize urinary bladder and ureterovesical junction issues in children, but has limitations. It is valuable for monitoring kidney disease but not for initial diagnosis of urinary tract changes.
Area of Science:
- Pediatric Nephrology
- Diagnostic Imaging
Context:
- Sonography of the urinary bladder and ureterovesical junction was performed in 41 children.
- Evaluated conditions included distended bladder walls, ureteral dilations, ureteroceles, and rhabdomyosarcoma.
Purpose:
- To describe the sonographic findings of the ureterovesical junction and urinary bladder in pediatric patients.
- To assess the utility and limitations of sonography in diagnosing pediatric nephrourological conditions.
Summary:
- Sonographic imaging revealed ureteral dilations, ureteroceles, and rhabdomyosarcoma.
- Difficulties were encountered in visualizing ureters <6 mm wide and normal ureterovesical junctions.
- Sonography cannot assess vesicoureteral reflux.
Impact:
- Sonography is not recommended as an alternative to radiological methods for initial diagnosis of nephrourological changes in children.
- It is particularly valuable for clarifying renal insufficiency and for follow-up of pediatric nephrourological disease.
Abstract:
Sonography of the ureterovesical junction and of the urinary bladder is described on the basis of examinations of 41 children. This included all distended bladder walls, ureteral dilations, ureteroceles and a rhabdomyosarcoma. Sonographic imaging presents difficulties in visualising ureters less than 6 mm wide, and in case of normal uretero-vesical junctions. Sonography cannot assess a versicoureteral reflux. Sonography should not be used in the first diagnosis of nephrourological changes as an alternative to radiological methods, since this may result in overlooking relevant curable changes in children. Sonography is particularly valuable in clarifying renal insufficiency and in following up children with nephrourological disease.
