[Contrast sonography of the urinary tract in children]
Insights
Contrast sonography in children evaluated bladder contrast agents. Intravesical air contrast demonstrated superior echogenicity and duration compared to fluid contrasts for bladder imaging.
Area of Science:
- Pediatric radiology
- Medical imaging techniques
- Diagnostic sonography
Context:
- Contrast sonography is a valuable tool in pediatric imaging.
- Evaluating different contrast agents for bladder sonography is crucial for diagnostic accuracy.
- Voiding cystourethrography is a standard procedure for evaluating pediatric urinary tract issues.
Purpose:
- To compare the sonographic contrast effects of various solutions introduced into the bladder in healthy children.
- To assess the efficacy of iothalamate, saline, urine, and air as bladder contrast agents.
- To determine the optimal contrast agent for bladder sonography in pediatric patients.
Summary:
- Contrast sonography was performed on 14 healthy children using different bladder contrast agents before voiding cystourethrography.
- Solutions including iothalamate, urine, 0.9% saline, and air were introduced via catheter.
- Intravesical air contrast exhibited superior echogenicity and duration compared to all fluid-based mixture contrasts.
Impact:
- Findings suggest intravesical air contrast may be a superior method for bladder sonography in children.
- This research could lead to improved imaging protocols for pediatric urinary tract evaluations.
- Enhanced visualization through optimal contrast agents can improve diagnostic confidence and patient outcomes.
Abstract:
In 14 healthy children contrast sonography of the bladder was performed with various solutions prior to voiding cystourethrography. The solutions were introduced into the bladder via a bladder catheter. The contrast effects which occurred with iothalamate injections in the urine-filled bladder, with urine injections in the iothalamate-filled bladder, with injections of 0.9% saline solution, and with air injections into the iothalamate-filled bladder were sonographically demonstrated. In echogenicity and duration the intravesical air contrast was superior to all mixture contrasts in the bladder resulting from injections of the respective fluids.
