Artificial urinary sphincter surgery
Infection has been a frequent and serious complication of surgery, not only because of the infection per se, but also because infection can cause erosion of the urethra or bladder neck under the implant....
The infection may actually worsen the incontinence. The overall infection rate with AUS implants is 1–3%. Because of interactions between the host and the foreign body represented by the implant, infections can occur soon after the surgery, or months and even years later. New techniques using antibiotics and skin preparations have improved infection rates considerably.
Artificial anal sphincter surgery
This surgery is for a limited number of patients who have isolated sphincter deficiency. Patients must be chosen who have little co-morbidity (serious illnesses) and can be trained in the use of the pump. Although it is a fairly simple operation, some researchers report a 30% infection rate.

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.
