Insights
The AMS artificial sphincter offers a specific treatment for urinary incontinence in children. This study details the device and its use in a large pediatric group.
Area of Science:
- Urology
- Pediatric Surgery
- Biomedical Engineering
Background:
- Urinary incontinence presents diverse causes and treatment options.
- The AMS artificial sphincter is a specialized device for managing urinary incontinence.
Purpose of the Study:
- To describe the mechanical aspects of the AMS artificial sphincter.
- To present clinical outcomes of artificial sphincter use in pediatric patients.
Main Methods:
- Review of the mechanical design and components of the AMS artificial sphincter.
- Analysis of clinical data from a large cohort of pediatric patients treated with the device.
Main Results:
- Detailed explanation of the artificial sphincter's mechanism of action.
- Presentation of the authors' experience with the device in a significant number of children.
Conclusions:
- The AMS artificial sphincter has a defined role in managing specific cases of pediatric urinary incontinence.
- Clinical experience supports its utility in a select pediatric population.
Abstract:
Urinary incontinence has many etiologies and a similarly varied and wide-ranging spectrum of therapeutic alternatives. The AMS artificial sphincter represents one of these options that has a distinct, albeit limited, place in certain patients. The authors outline the mechanical details of these devices and present their own clinical experience in a large pediatric population.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
