Stress incontinence is very common among women, with childbirth and menopause increasing the risk for it. It can also affect men who have had surgical procedures for prostate disease, especially cancer. Urge incontinence, also called overactive bladder, is marked by a need to urinate frequently. There are many causes of urge incontinence, including medical conditions (benign prostatic hyperplasia, Parkinson. Bladder obstruction and inactive bladder muscle can cause overflow incontinence. Risk factors include certain types of medications, benign prostatic hyperplasia, and nerve damage. Functional incontinence is incontinence due to mental or physical disabilities that impair a person. Many people have more than one type of urinary incontinence. Treatment of Urinary Incontinence. Treatment options for urinary incontinence depend on the type of incontinence and the severity of the condition. Treatments include: Lifestyle Changes. Significant weight gain can weaken pelvic floor muscle tone, leading to urinary incontinence. Losing weight through healthy diet and exercise is important. Regulating the time you drink fluids and avoiding alcohol and caffeine are also helpful. Behavioral Techniques. Pelvic floor exercises (Kegel exercises) can help strengthen the muscles of the pelvic floor that support the bladder and close the sphincter. Bladder training can help patients learn to delay urination. Medications. Drugs, such as oxybutynin (Ditropan, generic) and tolterodine (Detrol), are mainly used to treat urge incontinence. Surgery. Many types of surgical procedures are used to correct anatomical problems that contribute to severe urinary incontinence. The American Urological Association. According to a recent study, drugs for urge urinary incontinence only help about 2. Drug Approvals. In 2. Food and Drug Administration (FDA) approved mirabegron (Myrbetriq), a new type of drug for treatment of overactive bladder. In 2. 01. 1, the FDA approved Botox injections to treat urinary incontinence caused by neurological conditions such as spinal cord injury and multiple sclerosis. Introduction. Urinary incontinence is the inability to control urination. It may be temporary or permanent, and can result from a variety of problems in the urinary tract. Urinary incontinence is generally divided into four types: Stress incontinence. Urge incontinence. Overflow incontinence. Functional incontinence. Often, more than one type of incontinence is present. When this occurs, it is called mixed incontinence. Because incontinence is a symptom, rather than a disease, it is often hard to determine the cause. In addition, a variety of conditions may be the cause. Normal Urination. The urinary system helps to maintain proper water and salt balance throughout the body: The process of urination begins in the two kidneys, which process fluids and eliminate water and waste products to produce urine. Urine flows out of the kidneys into the bladder through two long tubes called ureters. The bladder is a sac that acts as a reservoir for urine. It is lined with a tissue membrane and enclosed in a powerful muscle called the detrusor. The bladder rests on top of the pelvic floor. This is a muscular structure similar to a sling running between the pubic bone in front to the base of the spine. The bladder stores the urine until it is eliminated from the body via a tube called the urethra, which is the lowest part of the urinary tract. In women it leads directly out.)The connection between the bladder and the urethra is called the bladder neck. Strong muscles called sphincter muscles encircle the bladder neck (the smooth internal sphincter muscles) and urethra (the fibrous external sphincter muscles). There are two phases: the emptying phase and the filling and storage phase. The Filling and Storage Phase. When a person has completed urination, the bladder is empty. This triggers the filling and storage phase, which includes both automatic and voluntary actions. Automatic Actions. The automatic signaling process in the brain relies on a pathway of nerve cells and chemical messengers (neurotransmitters) called the cholinergic and adrenergic systems. Important neurotransmitters include serotonin and noradrenaline. This pathway signals the detrusor muscle surrounding the bladder to relax. As the muscles relax, the bladder expands and allows urine to flow into it from the kidney. As the bladder fills to its capacity (about 8 - 1. Voluntary Actions. As the bladder swells, the person becomes conscious of a sensation of fullness. In response, the individual holds the urine back by voluntarily contracting the external sphincter muscles, the muscle group surrounding the urethra. These are the muscles that children learn to control during the toilet training process. When the need to urinate becomes greater than one's ability to control it, urination (the emptying phase) begins. The Emptying Phase. This phase also involves automatic and conscious actions. Automatic Actions. When a person is ready to urinate, the nervous system initiates the voiding reflex. The nerves in the spinal cord (not the brain) signal the detrusor muscle to contract. At the same time, nerves are also telling the involuntary internal sphincter (a strong muscle encircling the bladder neck) to relax. With the bladder neck now open, the urine flows out of the bladder into the urethra. Voluntary Actions. Once the urine enters the urethra, a person consciously relaxes the external sphincter muscles, which allows urine to completely drain from the bladder. The female and male urinary tracts are relatively the same except for the length of the urethra. High- impact exercise poses the greatest risk for leaking. But stress incontinence can occur with even minor activities, such as: Coughing. Sneezing. Laughing. Running (sometimes even standing can produce leakage)Lifting. Leakage stops when the stress ends. If the leakage persists, it is more likely to be urge incontinence. Causes of Stress Incontinence in Women. Stress incontinence occurs because the internal sphincter does not close completely. In both men and women, the aging process causes a general weakening of the sphincter muscles and a decrease in bladder capacity. However, the causes of stress incontinence may be different in men and women. In women, stress incontinence is nearly always due to one or. In such cases, pregnancy and childbirth strain and weaken the muscles of the pelvic floor causing a condition called urethral hypermobility. In urethral hypermobility the urethra does not close properly. It is one of the main causes of stress incontinence. Prolapsed uterus, in which the uterus protrudes into the vagina, occurs in about half of all women who have given birth. This condition can often cause incontinence. Injuries from previous surgeries can damage or weaken the bladder neck muscles. Causes of Stress Incontinence in Men. Prostate treatments can impair the sphincter muscles and. Surgery or radiation for prostate cancer. Some degree of incontinence occurs in nearly all male patients for the first 3 - 6 months after radical prostatectomy. Within a year after the procedure, most men regain continence, although some leakage may still occur. Surgery for benign prostatic hyperplasia. Stress incontinence can occur in some men after transurethral resection of the prostate (TURP), the standard treatment for severe benign prostatic hyperplasia (BPH). Because studies often combine the two types of incontinence, it is not always clear which predominates. Urge Incontinence. Urge incontinence (also called hyperactive, irritable, or overactive bladder) is the need to urinate frequently. People with overactive bladder may go to the bathroom more than 8 times over 2. In some cases, urge incontinence occurs only at night. This is called nocturnal enuresis. All cases of urge incontinence involve an overactive bladder. This occurs when the detrusor muscle, which surrounds the bladder, contracts inappropriately during the filling stage. When this happens, the urge to urinate cannot be voluntarily suppressed, even temporarily. Conditions that can cause urge incontinence include: Benign prostatic hyperplasia (BPH), also called. Overflow incontinence can be due to a number of conditions: A partial obstruction. In this case the urine cannot flow completely out of the bladder, so it never fully empties. An inactive bladder muscle. In contrast to urge incontinence (overactive bladder), with overflow incontinence the bladder is less active than normal, not more. It cannot empty properly and so becomes distended, or swollen. Eventually this distention stretches the internal sphincter until it opens partially and leakage occurs. Causes of. Diabetes, multiple sclerosis, and shingles also can cause this problem. Functional Incontinence. Patients with functional incontinence have mental or physical disabilities that keep them from urinating normally, although the urinary system itself is structurally intact. Conditions that can lead to functional incontinence include: Parkinson's disease. Alzheimer's disease and other forms of dementia. Mental confusion may prevent both recognition of the need to void and locating a bathroom. Severe depression. In such cases, people may become incontinent because they have difficulty with self- control. Risk Factors. About 2. American women and 6 million men have urinary incontinence or have experienced it at some time in their lives. The number, however, may actually be higher because many patients are often reluctant to discuss incontinence with their doctors. Some of the main risk factors for urinary incontinence include: Female sex. Older age. Having given birth or having had prostate problems or prostate surgery. Being overweight. Neurological disorders (such as stroke or multiple sclerosis)Gender. Urinary incontinence is far more common among women than men. This is because pregnancy and childbirth, menopause, and the anatomical shape of the female urinary tract all increase the risk for incontinence.
