What causes urinary retention?
urinary memory can result from
- obstruction of the urethra
- nerve problems
- weakened bladder muscles
Obstruction of the Urethra
obstacle of the urethra causes urinary retentiveness by blocking the convention urine flow out of the body. Conditions such as benign prostate hyperplasia — besides called BPH — urethral stenosis, urinary tract stones, cystocele, rectocele, constipation, and certain tumors and cancers can cause an obstacle.
Benign prostatic hyperplasia. For men in their 50s and 60s, urinary retentiveness is frequently caused by prostate expansion due to benign prostate hyperplasia. Benign prostate hyperplasia is a checkup condition in which the prostate gland gland is enlarged and not cancerous. The prostate is a walnut-shaped gland that is share of the male generative system. The gland surrounds the urethra at the neck of the bladder. The bladder neck is the sphere where the urethra joins the bladder. The prostate goes through two independent periods of growth. The first occurs early on in puberty, when the prostate doubles in size. The second phase of growth begins around long time 25 and continues during most of a man ‘s life. Benign prostate hyperplasia often occurs with the second phase of growth. As the prostate gland enlarges, the gland presses against and pinches the urethra. The bladder wall becomes blockheaded. finally, the bladder may weaken and lose the ability to empty wholly, leaving some urine in the bladder. Urethral stricture. A urethral stenosis is a pin down or closure of the urethra. Causes of urethral stenosis include ignition and scar tissue from operating room, disease, recurring UTIs, or wound. In men, a urethral stricture may result from prostatitis, scarring after an wound to the penis or perineum, or surgery for benign prostate hyperplasia and prostate gland cancer. Prostatitis is a frequently irritating condition that involves ignition of the prostate and sometimes the areas around the prostate. The perineum is the sphere between the anus and the sex organs. Since men have a longer urethra than women, urethral stricture is more common in men than women.1 surgery to correct pelvic organ prolapse, such as cystocele and rectocele, and urinary dissoluteness can besides cause urethral stricture. The urethral stenosis often gets better a few weeks after operating room. urethral stricture and acute or chronic urinary retentiveness may occur when the muscles surrounding the urethra do not relax. This condition happens largely in women. Urinary tract stones. urinary tract stones develop from crystals that form in the urine and build up on the inside surfaces of the kidneys, ureters, or bladder. The stones formed or lodged in the bladder may block the open to the urethra. Cystocele. A cystocele is a bulge of the bladder into the vagina. A cystocele occurs when the muscles and supportive tissues between a charwoman ‘s bladder and vagina weaken and stretch, letting the bladder sag from its normal stead and bulge into the vagina. The abnormal side of the bladder may cause it to press against and pinch the urethra.
Rectocele. A rectocele is a bulge of the rectum into the vagina. A rectocele occurs when the muscles and supportive tissues between a womanhood ‘s rectum and vagina weaken and stretch, letting the rectum sag from its normal position and bulge into the vagina. The abnormal position of the rectum may cause it to press against and pinch the urethra. Constipation. Constipation is a condition in which a person has fewer than three intestine movements a week or has bowel movements with stools that are hard, dry, and small, making them irritating or unmanageable to pass. A person with stultification may feel bloated or have pain in the abdomen — the area between the chest and hips. Some people with stultification often have to strain to have a intestine apparent motion. Hard stools in the rectum may push against the bladder and urethra, causing the urethra to be pinched, particularly if a rectocele is introduce. Tumors and cancers. Tumors and cancerous tissues in the bladder or urethra can gradually expand and obstruct urine flow by pressing against and pinching the urethra or by blocking the bladder exit. Tumors may be cancerous or noncancerous .
urinary retentiveness can result from problems with the nerves that control the bladder and sphincters. many events or conditions can interfere with boldness signals between the brain and the bladder and sphincters. If the nerves are damaged, the mind may not get the signal that the bladder is wide. even when a person has a full moon bladder, the bladder muscles that wedge urine out may not get the signal to push, or the sphincters may not get the signal to relax. People of all ages can have nerve problems that interfere with bladder routine. Some of the most common causes of heart problems include
- vaginal childbirth
- brain or spinal cord infections or injuries
- multiple sclerosis
- pelvic injury or trauma
- heavy metal poisoning
In addition, some children are born with defects that affect the coordination of nerve signals among the bladder, spinal cord, and brain. Spina bifida and other parentage defects that affect the spinal anesthesia cord can lead to urinary retention in newborns. many patients have urinary retentiveness correct after operation. During operating room, anesthesia is often used to block annoyance signals in the nerves, and fluid is given intravenously to compensate for possible rake loss. The combination of anesthesia and intravenous ( IV ) fluid may result in a full bladder with mar nerve serve, causing urinary memory. normal bladder nerve affair normally returns once anesthesia wears off. The affected role will then be able to empty the bladder wholly .
respective classes of medications can cause urinary retentiveness by interfering with steel signals to the bladder and prostate. These medications include
other medications associated with urinary retentiveness include Over-the-counter coldness and allergy medications that contain decongestants, such as pseudoephedrine, and antihistamines, such as diphenhydramine, can increase symptoms of urinary retention in men with prostate gland expansion .
Weakened Bladder Muscles
Aging is a common lawsuit of weaken bladder muscles. Weakened bladder muscles may not abridge powerfully enough or retentive enough to empty the bladder wholly, resulting in urinary retention .
