Abstract:
The first hydraulic artificial urinary sphincter came into clinical use in 1972. The original prototype has undergone many modifications resulting from advances in mechanical design, applications of new technology, and clinical experience. This evolutionary process has culminated in the AS800, the most frequently used hydraulic artificial urinary sphincter in the U.S. today. Although the AS800 device most closely approximates the biological urinary sphincter, clinical demands for an ever more ideal urinary sphincter require the ongoing improvement of this device.

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...
