Urinary incontinence is defined as involuntary leakage of urine.
Stress urinary incontinence (SUI): involuntary urine leakage on exertion or with sneezing or coughing. Urge urinary incontinence: women have difficulty postponing urination urges and generally must promptly empty their bladder on cue and without delay. If urge urinary incontinence is objectively demonstrated by cystometric evaluation, the condition is known as detrusor overactivity (DO).
Mixed urinary incontinence : When both stress and urge components are present, it is called.
Prevalence of 25 - 55 %. Among women with urinary incontinence, the most common condition is stress incontinence, which represents 29 to 75 %of cases. Detrusor overactivity accounts for up to 33 % of incontinence cases. whereas the remainder is attributable to mixed forms.

Pressure Transmission Urethral Support
In an ideally supported urogenital tract, increases in intra-abdominal pressure are equally transmitted to the bladder, bladder base, and urethra. In women who are continent, increases in downward-directed pressure from cough, laugh, sneeze, and Valsalva maneuver are countered by supportive tissue tone provided by the levator ani muscle and vaginal connective tissue.
In those with a weakened supportive "backboard", however, downward forces are not countered. This leads to funneling of the urethrovesical junction, a patent urethra, and in turn, urine leakage.
Urethral support is integral to continenc (1) ligaments along the lateral aspects of the urethra, termed the pubourethral ligaments; (2) the vagina and its lateral fascial condensation; (3) the arcus tendinous fascia pelvic; (4) levator ani muscles. With loss of urethral support, the urethra's ability to close against a firm supportive backboard is diminished.

Urge Incontinence Stress Incontinence Symptom No Yes Urgency No Yes Frequency with urgency Yes No Urine leakage with increased intra-abdominal pressures smallLarge Amount of urinary leakage with each incontinence episode YesOften No Ability to reach the toilet in time following an urge to void Seldom Usually Waking to void at night
General Inspection and Neurologic Evaluation evidence of atrophy. neurologic evaluation of the perineum: bulbocavernosus reflex normal circumferential anal sphincter contraction, colloquially called an "anal wink",
Medications: Pharmaceutical treatment plays a minor role in the treatment of women with SUI. imipramine is reasonable to aid urethral contraction and closure. Recently, duloxetine a selective serotonin and norepinephrine reuptake inhibitor, has been evaluated for the treatment of SUI
