Between 2004 and 2005 there was a personal experience in the similar technique by group of surgeons. That technique included coring out the intersphinteric fistula tract from the external opening to the external sphincter, excision of the intersphincteric fistula tract and suture of the internal sphincter defect through the intersphincteric plane.
The muscle helps maintain continence of urine along with the internal urethral sphincter which is under control of the autonomic nervous system.The external sphincter muscle prevents urine leakage as the muscle is tonically contracted via somatic fibers that originate in Onuf's nucleus and pass through sacral spinal nerves S2-S4 then the pudendal nerve to synapse on the muscle.
The two muscles are either the male or female external urethral sphincter and the internal urethral sphincter. When either of these muscles contracts, the urethra is sealed shut. The external urethral sphincter originates at the ischiopubic ramus and inserts into the intermeshing muscle fibers from the other side.
Primary sphincter repair is inadequate in most women with obstetric ruptures following vaginal delivery. Residual sphincter defects remain in most and around 50% remain incontinent. If there is a residual sphincter defect following the operation (as demonstrated by endoanal ultrasonography), then the procedure may be repeated. [4] [5]
Another procedure to treat incontinence is the use of an artificial urinary sphincter, more used in men than in women. In this procedure, the surgeon enters and wraps the cuff of the artificial urinary sphincter around the urethra, in the same manner a blood pressure cuff wraps around your arm. The device includes a pump implanted under the ...
External sphincter muscle may refer to: External anal sphincter; External sphincter muscle of female urethra; External sphincter muscle of male urethra
The pudendal nerve is the main nerve of the perineum. [1]: 274 It is a mixed (motor and sensory) nerve and also conveys sympathetic autonomic fibers.It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.
The external anal sphincter (or sphincter ani externus) is an oval tube of skeletal muscle fibers. [1] Distally, it is adherent to the skin surrounding the margin of the anus. [2] It exhibits a resting state of tonical contraction [1] and also contracts during the bulbospongiosus reflex. [3] [4] [5] [6]
