Abstract
Stress urinary incontinence is the leakage of urine on stress
or exertion which is the most common cause of
incontinence in young women and second in the old women.
Pelvic muscle dysfunction and sagging as a result of elderly,
obesity, pregnancy and vaginal delivery causes SUI because of
the disrupted ligament of the urethra and weakness of pelvic
muscle floor.
This sagging of the pelvic floor leads to abnormal
descent of the urinary bladder, uterus, vagina and rectum
therefore increase incidence of SUI. The pelvis is categorized
into three components anterior compartment contains bladder
and urethra, middle compartment is containing vagina and
uterus and lastly posterior compartment contains anus and
rectum. The tissues that anchoring these compartments are the
ligaments and the muscles of the pelvic floor.
The damage to the supporting structures of these
compartments leads to SUI. The degree of the disruption of the
urethral ligaments and puboperineal muscles should be
estimated in the SUI cases to be diagnosed and managed
correctly. The conventional ways of diagnosis of pelvic floor
dysfunction include voiding cystourethrogram, ultrasound and urodyamic but in recent years with advances in technology
MRI proved to be the best to detect the degree of the floor
dysfunction and to know which structure is damaged as
dynamic MRI can detect and grade the pelvic floor relaxation
by using HMO system, estimate width of the Levator hiatus and
assessment of the iliococcygeal angle. Endovaginal MRI
appears to be the most precise way to know the causing
structural damage by imaging the urethra and its anchoring
ligaments, detecting and estimating the damage to the pubic
component of the Levator ani muscle, and to detect the damage
of three levels of fascial support of DeLancey.
