Stress incontinence

Stress incontinence, also known as stress urinary incontinence (SUI) or effort incontinence is a form of urinary incontinence. It is due to insufficient strength of the closure of the bladder. Stress incontinence, also known as stress urinary incontinence (SUI) or effort incontinence is a form of urinary incontinence. It is due to insufficient strength of the closure of the bladder. It is the loss of small amounts of urine associated with coughing, laughing, sneezing, exercising or other movements that increase intra-abdominal pressure and thus increase pressure on the bladder. The urethra is supported by fascia of the pelvic floor. If this support is insufficient, the urethra can move downward at times of increased abdominal pressure, allowing urine to pass. Most lab results such as urine analysis, cystometry and postvoid residual volume are normal. Some sources distinguish between urethral hypermobility and intrinsic sphincter deficiency. The latter is more rare, and requires different surgical approaches. Stress incontinence is rare in men. The most common cause is as a post-surgical complication following a prostatectomy. In women, physical changes resulting from pregnancy, childbirth, and menopause often contribute to stress incontinence. Stress incontinence can worsen during the week before the menstrual period. At that time, lowered estrogen levels may lead to lower muscular pressure around the urethra, increasing chances of leakage. The incidence of stress incontinence increases following menopause, similarly because of lowered estrogen levels. In female high-level athletes, effort incontinence occurs in all sports involving abrupt repeated increases in intra-abdominal pressure that may exceed perineal floor resistance. Some behavioral changes can improve stress incontinence. It is recommended to decrease overall consumption of liquids and avoid drinking caffeinated beverages because they irritate the bladder. Spicy foods, carbonated beverages, alcohol and citrus also irritate the bladder and should be avoided. Quitting smoking can also improve stress incontinence because smoking irritates the bladder and can induce coughing (putting stress on the bladder). Weight loss in overweight women reduced stress incontinence, in women with a Body Mass Index (BMI) over 25 and at least 10 episodes of urinary incontinence per week. With exercise and restricted diet they had a 70% or greater reduction in overall incontinence episodes. One of the most common treatment recommendations includes exercising the muscles of the pelvis. Kegel exercises to strengthen or retrain pelvic floor muscles and sphincter muscles can reduce stress leakage. Patients younger than 60 years old benefit the most. The patient should do at least 24 daily contractions for at least 6 weeks. It is possible to assess pelvic floor muscle strength using a Kegel perineometer.
