Index • Types of Urinary Incontinence(UI) in Women • Causes & Affects • Treatments • Study • Results
Types of UI - Involuntary loss of urine(International Continence Society (ICS) • Stress Urinary Incontinence (SUI), primary focus – Weakened pelvic floor muscles • Urge Incontinence – Involuntarily release of urine due to feeling the need or urge to urinate • Neurogenic – Defective CNS inhibitor response • Functional – Has the urge to urinate, but cannot physically make it to bathroom due to limited mobility. – Confusion, dementia, poor eyesight, poor mobility, poor dexterity, etc. • Overflow – Inability to stop bladder from “dribbling”, feeling as bladder is “overflowing” • Mixed – Common in older females, retention of urination, sometimes caused by extreme constipation (pressure against bladder), medications, urinary tract infections
SUI Causes & Affects • Lack of strength of the pelvic floor muscles – Affects normally during excess intra-abdominal pressure: coughing, laughing, sneezing, exercising, and other activities that increase pressure – Urethra is supported by fascia of pelvic floor; in increased intraabdominal pressure, urethra can drop causing involuntary release of urine – In women: menopause, childbirth, and pregnancy • Affects – Quality of life reduced • Emotional • Social • Physical • Sexual
Treatments • Nonsurgical (primary focus) – Pelvic Floor Training (a. k. Kegel exercises), is highly urged by doctors before seeking surgical means of treatment along with/without biofeedback, electro-stimulation, and vaginal cones • Surgical – Modified Burch Colposuspension • Attaching via a tension free fashion of the vaginal wall to the Coopers’ ligament – Retropubic Tension-free vaginal tape • placing below the urethra a polypropylene mesh tape – Transobturator urethral tape suspension • Similar to the retropubic tension-free vaginal tape but is done by inserting the tape via the small incision points in the groin
Nonsurgical Treatment • Pelvic Floor Training (Kegel exercises) – Strengthening by contacting and releasing the pubococcygeus muscles • Helps tighten the sphincter that controls urinary disposal • Biofeedback – Devices are used to make the user aware of various physiological functions – Typically done using a sensor and feedback monitor – Electromyograph(EMG), feedback thermometer, electrodermograph, electrocardiograph(ECG), etc. • Electrical Stimulation – Electrodes are attached to the vagina externally(interferential) or internally – The current forces the muscles to contract similarly to exercising them • Vaginal Cones – Weighted cones placed in the vagina and held in place by contracting
Study • Reviewed 24 studies: 17 of which were Randomized Controlled Trials(RCT) and 7 non-RCT • Only peer-reviewed studies in English from 1995 -2005 were included (mainly due to methodology and updated medical techniques • Subjects were adult females of all age groups, self-report, or show signs of SUI, were not pregnant nor within six weeks post-partum • Different studies examined possible combinations of pelvic floor muscle training(PFMT), biofeedback(BF), electrical stimulation(ES), and vaginal weights(VW) • Cured and cured/improvement are described as such;
Outcome • Since many of the studies were based on personal opinion, some of the data was regarded as low quality studies – With this in mind, all the studies examined had a positive feedback about Pelvic Floor Muscle Training • There is strong evidence that SUI treated with PFMT, PFMT+BF+ES, has a high rate of effectiveness (73% cured, 97%, cured/improved • The main factors that may have affected the results were: – Age, initial severity of incontinence, compliance w/the home training program, and initial PFM strength • Strengthening the pelvic floor muscles led to reduced symptoms of SUI – 1 week - 6 months = changes in incontinence are noticeable – Improvement in PFM strength may take at least 3 months
