Stress urinary incontinence is a common problem related to the function of the urethral sphincter. Weak pelvic floor muscles, intrinsic sphincter damage, or damage to the surrounding nerves and tissue can make the urethral sphincter incompetent, and subsequently it will not close fully, leading to stress urinary incontinence.
Urinary incontinence can result from both urologic and non-urologic causes. Urologic causes can be classified as either bladder dysfunction or urethral sphincter incompetence and may include detrusor overactivity, poor bladder compliance, urethral hypermobility, or intrinsic sphincter deficiency.
Also, when you have an erection, the spongey tissue around your urethra, known as the corpora cavernosa, expands, urologist Dr. Rena Malik, M.D. explained in a recent video on her YouTube channel ...
Another procedure to treat incontinence is the use of an artificial urinary sphincter, more used in men than in women. In this procedure, the surgeon enters and wraps the cuff of the artificial urinary sphincter around the urethra, in the same manner a blood pressure cuff wraps around your arm. The device includes a pump implanted under the ...
Bladder sphincter dyssynergia (also known as detrusor sphincter dyssynergia (DSD) (the ICS standard terminology agreed 1998) [1] and neurogenic detrusor overactivity (NDO)) is a consequence of a neurological pathology such as spinal injury [2] or multiple sclerosis [3] which disrupts central nervous system regulation of the micturition (urination) reflex resulting in dyscoordination of the ...
Alpha-adrenergic agonists may cause urinary retention by stimulating the contraction of the urethral sphincter. Calcium channel blockers may decrease the contractility of the smooth muscle tissue in the urinary bladder, causing urinary retention with overflow incontinence. Epidural anesthesia and delivery also can cause the overflow incontinence.
A urethral bulking injection is one type of treatment for incontinence in women. Urethral bulking injections are considered by a clinician when the woman has urinary sphincter dysfunction, urethral hypermobility, persistent stress urinary incontinence after a urethral sling or urethropexy, or stress urinary incontinence in women who cannot undergo surgery due to other illnesses or conditions.
This can cause the inability to void urine even if the bladder is full and cause a large bladder capacity. The internal urinary sphincter can contract normally, however urinary incontinence is common. This type of neurogenic bladder is caused by damage to the peripheral nerves that travel from the spinal cord to the bladder. [5]
