Ultrasound scanning for monitoring childhood hydronephrosis
Insights
Ultrasound scanning effectively assesses pediatric hydronephrosis by measuring renal pelvis diameter before and after fluid intake. This method shows improvement during fasting, complementing traditional imaging and reducing the need for further radiological tests.
Area of Science:
- Pediatric Urology
- Diagnostic Imaging
- Nephrology
Background:
- Hydronephrosis in children requires accurate assessment for effective management.
- Traditional radiological investigations like intravenous pyelography (IVP) have limitations.
- A modified ultrasound technique was explored to enhance diagnostic capabilities.
Observation:
- Kidney ultrasound scans were performed on four children with confirmed hydronephrosis.
- A novel approach involved scanning before and after significant fluid consumption.
- The anteroposterior diameter of the renal pelvis served as the primary metric for hydronephrosis severity.
Findings:
- Ultrasound demonstrated a reduction and disappearance of renal pelvis dilatation during fasting periods.
- Pronounced dilatation persisted after fluid intake and during IVP, indicating dynamic changes.
- The modified ultrasound technique showed good correlation with simultaneous IVP results.
Implications:
- Ultrasound scanning is a valuable adjunct in the urological evaluation of pediatric hydronephrosis.
- This method can potentially decrease the number of radiological investigations needed.
- Dynamic ultrasound assessment offers insights into renal pelvis behavior related to fluid status.
Abstract:
Ultrasound scanning of the kidneys in four children with radiologically proven hydronephrosis was undertaken with a new modification: scanning before and after copious intake of fluid. The anteroposterior diameter of the renal pelvis was used as an index of the hydronephrosis. Alterations in the dilatation were followed over a long period. Good agreement with simultaneous IVP was found. Improvement in the degree of hydronephrosis was apparent by reduction and disappearance of the dilatation of the pelvis during fasting as assessed by ultrasonic scanning, although pronounced dilatation was still observed after copious intake of fluid and at IVP. The results indicate that ultrasound scanning is a valuable supplement in the urological evaluation in children and that it can reduce significantly the number of radiological investigations required.
