Summary
Designing an ideal artificial urinary sphincter can significantly improve the quality of life for severe urinary incontinence patients. This review explores current research and future optimization strategies for artificial urinary sphincters.
Area of Science:
- Urology
- Biomedical Engineering
- Medical Device Design
Background:
- Urinary incontinence significantly impacts patient quality of life.
- Conservative treatments suit mild cases; severe cases benefit from artificial urinary sphincters.
Purpose of the Study:
- To review current research on artificial urinary sphincters.
- To identify areas for optimization in artificial urinary sphincter design and manufacturing.
Main Methods:
- Systematic literature search using PRISMA guidelines.
- Review of artificial urinary sphincters based on activation methods.
- Analysis of existing device deficiencies.
Main Results:
- Current artificial urinary sphincters have limitations.
- Future optimization involves individual improvements, engineering design, and manufacturing process enhancements.
Conclusions:
- An idealized artificial urinary sphincter is crucial for improving patient quality of life.
- Further research and evidence are needed to fully realize the potential of advanced artificial urinary sphincters.

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
138
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:23Urinary Bladder
984
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
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...

01:16Urethra
1.2K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

01:26The Micturition Reflex
753
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
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...
