Chronic urinary retention that is due to bladder blockage which can either be as a result of muscle damage or neurological damage. [7] If the retention is due to neurological damage, there is a disconnect between the brain to muscle communication, which can make it impossible to completely empty the bladder. [ 7 ]
The bladder (from Old English blædre 'bladder, blister, pimple') is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. [1] [2] In humans, the bladder is a distensible organ that sits on the pelvic floor.
Without diagnostic evaluation, the cause of underactive bladder is unclear, as there are multiple possible causes. UAB symptoms can accurately reflect impaired bladder emptying due either to DU or obstruction (normal or large storage volumes, elevated post-void residual volume), or can result from a sense of incomplete emptying of a hypersensitive bladder (small storage volumes, normal or ...
Bladder cancer makes up about 4% of cancers, most commonly affecting people 55 and older. While rates for bladder cancer are dropping, it’s still important to know what the most common signs of ...
Bladder outlet obstruction is included in the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). CAKUT is the most common cause of birth defects, occurring in 1 out of 1000 live births, and accounts for approximately half of all cases of chronic kidney disease and end-stage renal disease in children.
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows urination. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
Decline in bladder outlet is the process of gradual atrophy in the distal structures to the bladder in the urinary system. [1] It happens along with atrophy of the reproductive system in females. It is one of the contributing factors for disorders like stress incontinence. [2] It is commonly associated with decline in urethral resistance ...
The bladder needs to be adequately distended with contrast medium. [1] 300 mL or more are generally recommended. [1] The study has two films. One film is taken when the bladder is adequately distended and filled with contrast. [1] The next film is taken after the bladder is emptied without the assistance of a foley catheter. [1]
