Fiber types in the striated urethral and anal sphincters. Seven normal human striated urethral and anal sphincters obtained by autopsy were examined using histochemical techniques. In both the urethral sphincter and the subcutaneous s. A comparative study of various electrodes in electromyography of the striated urethral and anal sphincter in children. Carbon dioxide cystometry was carried out in the supine and the erect position and combined with simultaneous electromyography EMG. The external urethral sphincter Correlation between them was good, as was reproducibility.
Inflatable artificial sphincter
Inflatable artificial sphincter: MedlinePlus Medical Encyclopedia
Artificial sphincter insertion surgery is the implantation of an artificial valve in the genitourinary tract or in the anal canal to restore continence and psychological well being to individuals with urinary or anal sphincter insufficiency that leads to severe urinary or fecal incontinence. This procedure is useful for adults and children who have severe incontinence due to lack of muscle contraction by either the urethral sphincter or the bowel sphincter. The primary work of the lower urinary tract and the colon is the storage of urine and waste, respectively, until such time as the expulsion of urine or feces is appropriate. These holding and expelling functions in each system require a delicate balance of tension and relaxation of muscles, especially those related to conscious control of the act of urination or defecation through the valve-like sphincter in each system. Both types of incontinence have mechanical causes related to reservoir adequacy and sphincter, or "gatekeeper" control, as well as mixed etiologies in the chemistry, neurology, and psychology of human makeup. The simplest bases of incontinence lie in the mechanical components of reservoir mobility and sphincter muscle tone. These two factors receive the most surgical attention for both urinary and fecal incontinence.
The Artificial Bowel Sphincter (ABS)
A surgeon certified in general surgery by the American Board of Surgery has training, knowledge and experience related to the diagnosis and comprehensive management of surgical conditions. The device consists of three parts:. The ABS is implanted in the operating room.
Sphincters are muscles that allow your body to hold in urine. An inflatable artificial man-made sphincter is a medical device. This device keeps urine from leaking. It is used when your urinary sphincter no longer works well. When you need to urinate, the cuff of the artificial sphincter can be relaxed.
