Effects of Sacral Neuromodulation on Urinary and Fecal Incontinence
Background:
Fecal incontinence is defined as involuntary passage of stool through the anus. It may vary from soiling to complete evacuation. This involuntary loss of feces, flatus or urge incontinence adversely affects quality of life. Urinary urge incontinence is characterized by symptoms of frequency, urgency and urge incontinence (either alone or in combination). Urgency frequency syndrome is defined as symptoms of frequency and urgency without incontinence episodes.
Objectives:
To evaluate the efficacy of sacral neuromodulation on these pathologies.
Methods:
Following a detailed investigation, 51 patients with either urinary or fecal incontinence, or both, who did not respond to medical and behavioral treatment were offered the temporary implant. Of the 51 patients 40 showed improvement and advanced for a permanent device.
Results:
After a mean follow-up of 5 years (range 1-8), there was a significant reduction in the number of incontinence episodes (P < 0.0001), and the number of pads used also declined significantly (P < 0.0001). A marked improvement in quality of life was reported by 71.4% of the women and 58.3% of the men.
Conclusions:
Sacral neuromodulation as shown in this study appears to be a promising treatment for urinary and fecal incontinence and can dramatically improve patients' quality of life.

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...
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...
