Artificial urinary sphincter surgery
One problem with the urinary sphincter implant is failure. If the device fails, or the cuff erodes, the surgery must be repeated. In a study published in 2001, 37% of women had the implant after an...
average of seven years, but 70% had the original or a replacement and 82% were continent. Studies on men report similar findings. Malfunction has improved with advances in using a narrower cuff. In one large study encompassing one surgeon over 11 years, the re-operative rate of AUS related to malfunction in men was 21%. Over 90% of patients were alive with a properly functioning device.
Another problem with the surgery is urinary voiding. This may be difficult initially due to postoperative edema caused by bruising of the tissue. In the majority of cases, urination occurs after swelling has receded.
AUS is a good alternative for children. The results of AUS in children range from 62–90%, with similar rates for both girls and boys.
Artificial anal sphincter surgery
Anal sphincter implant surgery has been successfully performed for many years. The device most often used has a cumulative failure rate of 5% over 2.5 years. The long-term functional outcome of artificial anal sphincter implantation for severe fecal incontinence has not been determined. However, adequate sphincter function is recovered in most cases, and the removal rate of the device is low. Most of the good results are dependent upon careful patient selection and appropriate surgical and operative management with a highly experienced surgical team.

Definition
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.
Purpose
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.
