The Micturition Reflex01:26

The Micturition Reflex

3.2K
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...

Anatomy of the Genitourinary System II: Bladder and Urethra

2.3K
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...

Urethra01:16

Urethra

5.3K
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...

Area of Science:

  • Biomedical Engineering
  • Urology
  • Medical Devices

Background:

  • Urinary incontinence affects over 300 million people globally.
  • Current technological solutions lack minimally invasive and effective restoration of continence.
  • Existing treatments often involve invasive procedures or do not fully restore function.

Purpose of the Study:

  • To design, fabricate, and test a novel artificial endourethral urinary sphincter.
  • To develop a device capable of fully restoring continence in a minimally invasive manner.
  • To create a solution applicable to both men and women, enhancing daily life.

Main Methods:

  • Design and fabrication of a unidirectional polymeric valve with magnetically activated opening pressure modulation.
  • Minimally invasive insertion and retraction procedure.
  • Bench testing and ex vivo testing on human cadavers.

Main Results:

  • The artificial urinary sphincter successfully restored full continence in tests.
  • The device demonstrated the ability to allow voluntary urination.
  • The system proved effective in both bench and ex vivo human cadaver models.

Conclusions:

  • The novel artificial endourethral urinary sphincter shows high potential for treating urinary incontinence.
  • The device offers a minimally invasive, effective, and adaptable solution for patients.
  • Successful restoration of continence and urination function can significantly improve patients' quality of life.
