The role of the bladder is to store and to empty urine. It should store urine at low pressures allowing for passage of urine easily out of the kidneys, down the ureters into the bladder. It should keep the urine without leaking or bothersome bladder sensations.
When it is a convenient time to urinate, bladder emptying should occur as an easy command from the brain to the bladder. The bladder muscle should contract, the pelvic floor should relax, and the bladder should empty fully.
Interruption of the bladder's functions can lead to irritation, fear of urine loss, poor quality of life, kidney failure, or infection. This article examines several types of bladder disorder along with their symptoms, diagnosis, and treatment.
Urinary incontinence - the loss of bladder control - is a common and often embarrassing problem. The severity of urinary incontinence ranges from occasionally leaking urine when you cough or sneeze to having sudden, unpredictable episodes of strong urinary urgency.
There are different types of urinary incontinence. These include:
Urge Urinary Incontinence
This is involuntary leakage with a sudden strong urge to urinate (for example, putting the key in the door on arrival home). This condition may cause you to have to urinate often. We recommend the following treatments, depending the patient's individual preferences and needs and based on prior attempts at treatment.
Stress Urinary Incontinence
This is the involuntary leakage on effort or exertion, such as coughing, sneezing or lifting. Stress incontinence occurs when the sphincter muscle at the bladder is weakened. The problem is especially noticeable when you let your bladder get too full. Most treatments are surgical, but all options are tailored to the patient's preferences, the severity of incontinence, as well as other physical exam findings such as prolapse (a relaxed bladder or rectum). Minimally invasive options are usually possible, so a fear of surgery should not prevent one from seeking treatment.
Mixed Urinary Incontinence
This is a combination of stress urinary incontinence and urge urinary incontinence.Treatment is tailored to symptoms and diagnostic testing, but basically a combination of the therapies mentioned for stress and urge urinary incontinence.
This is the over-stretching of the bladder and poor emptying leading to overflow of urine when the bladder reaches maximum capacity. If you frequently or constantly dribble urine, you may have overflow incontinence. With overflow incontinence, sometimes you may feel as if you never completely empty your bladder. When you try to urinate, you may produce only a weak stream of urine.
Non-emptying of the bladder can occur when the bladder muscle does not contract, or with a blockage of the bladder due to "cystocele", a muscle spasm of the sphincter muscle, or other causes. Treatment involves correction of bad voiding habits, correction of anatomy to its natural location (fixing prolapse or hernias) or teaching people how to empty their own bladder with a catheter placed in for two minutes to drain.
Overactive bladder is a condition that results from sudden, involuntary contraction of the muscle in the wall of the urinary bladder. Overactive bladder is also referred to as urge incontinence. Symptoms include:
Sometimes these symptoms respond to simple treatments. When the simple treatments fail, there are newer technologies that can markedly improve quality of life. In order of simplest to most complex, treatments are
The normal function of the urinary bladder is to store and expel urine in a coordinated, controlled fashion. This coordinated activity is regulated by the central and peripheral nervous systems. Neurogenic bladder is when the spinal cord, brain, or bladder nerves are not functioning properly and the bladder fails to store and empty urine as it should.
The treatment depends heavily on diagnostic testing (urodynamics) and patient preference. The primary concern is making sure the kidneys can drain urine safely into the bladder to prevent kidney damage. The second goal is to address quality of life issues, such as preventing unwanted leakage or wetting of urine.
