[Functional reconstruction of the striated sphincter muscle in the incontinent anus (author's transl)]
Abstract:
Anal sphincter reconstruction with muscle transplantation according to Thompson and transposition of the denervated gracilis muscle onto the surface of the pelvic floor muscles are described. The transplanted and transposed muscles are reinnervated by a collateral nerve from the adjacent functioning muscles. The follow-up examination of 16 cases of anal incontinence two years after anal sphincter reconstruction demonstrates in all but one case ontinence for firm feces and in most of them, continence for fluid feces. Reflectoric contractions of the new reconstructed sphincter can be demonstrated by myographic and manometric investigations. The advantages of dynamic sphincter reconstruction with muscular neurotization compared to other more static techniques are discussed.

Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

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...
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 urine...
