The Micturition Reflex01:26

The Micturition Reflex

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 urine...
Urinary Bladder01:23

Urinary Bladder

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...

Area of Science:

  • Neuroscience
  • Urology
  • Biomedical Engineering

Background:

  • Neurological diseases and injuries often impair bladder function, leading to incontinence or urinary retention.
  • The pudendal nerve plays a crucial role in bladder control, mediating both sensory and motor functions.

Purpose of the Study:

  • To review studies investigating pudendal afferent nerve stimulation for bladder control.
  • To assess the potential of this technique for restoring continence and micturition.

Main Methods:

  • Review of existing research on electrical stimulation of pudendal sensory fibers.
  • Analysis of studies focusing on bladder activation and emptying enhancement.

Main Results:

  • Pudendal nerve stimulation can modulate bladder activity, leading to inhibition or activation.
  • The technique shows promise in improving bladder emptying in cases of urinary retention.
  • Restoration of bladder emptying after spinal cord injury is a potential application.

Conclusions:

  • Pudendal afferent stimulation is a viable strategy for addressing bladder dysfunction.
  • Further research can optimize this approach for neurological conditions affecting bladder control.
