Artificial urinary sphincters in children: radiographic evaluation
Insights
Artificial urinary sphincters treat pediatric incontinence, but mechanical failures occur. Radiographic evaluation is crucial for diagnosing complications in children with these devices.
Area of Science:
- Pediatric Urology
- Radiology
- Medical Device Engineering
Background:
- Artificial urinary sphincters (AUS) are increasingly used for pediatric urinary incontinence.
- The radiopaque hydraulic fluid necessitates radiologist involvement in AUS evaluation.
- Despite design improvements, AUS devices are prone to mechanical failures and complications.
Purpose of the Study:
- To review the experience with artificial urinary sphincters in children.
- To outline a method for radiographic evaluation of AUS.
- To identify common complications and diagnostic errors associated with AUS.
Main Methods:
- Review of 34 artificial sphincters implanted in 31 children between 1973 and 1983.
- Analysis of radiographic evaluations for diagnosing AUS malfunction and complications.
Main Results:
- The study details common complications and examples of sphincter malfunction.
- Diagnostic errors to avoid during radiographic evaluation are presented.
- Experience with a cohort of pediatric AUS patients is analyzed.
Conclusions:
- Radiographic evaluation is essential for managing pediatric artificial urinary sphincters.
- Understanding common complications and diagnostic pitfalls improves patient care.
- This review provides insights into the long-term performance and management of AUS in children.
Abstract:
Use of the artificial urinary sphincter to treat incontinence in children has increased over the past decade. The hydraulic fluid used in this device is radiopaque, and the radiologist is directly involved in its evaluation. Despite advances in design and surgical technique, mechanical failures and other complications occur. Our experience with 34 artificial sphincters implanted in 31 children during 1973-1983 is reviewed, giving a method of radiographic evaluation, diagnostic errors to avoid, examples of sphincter malfunction, and common complications.
