The Micturition Reflex01:26

The Micturition Reflex

3.9K
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...

Urinary Bladder01:23

Urinary Bladder

4.6K
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...

Muscle Stimulation Frequency01:22

Muscle Stimulation Frequency

4.6K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Urodynamic Studies: Uroflowmetry01:19

Urodynamic Studies: Uroflowmetry

9.1K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Summary

A novel vaginal plug delivers electrical stimulation to pelvic floor muscles, triggered by abdominal pressure increases, to treat stress urinary incontinence. This study optimized stimulation parameters using coughs, a common cause of urine leakage.

  • To investigate the efficacy of the method during common activities causing urine loss, such as coughing.

Main Methods:

  • Development of a vaginal plug device with integrated pressure sensors.
  • Application of electrical stimulation to pelvic floor muscles.
  • Systematic determination of stimulation parameters (frequency, intensity, duration) during induced coughs.
  • Monitoring of abdominal pressure changes to trigger stimulation.

Main Results:

  • The study successfully identified optimal electrical stimulation parameters for pelvic floor muscle response.
  • The device demonstrated reliable triggering of stimulation in response to increased abdominal pressure.
