The x-axis is the volume of liquid and the y-axis is the intraluminal pressure of the bladder. In normal patients, the plot is a series of spikes whose local minimums form a non-linear curve resembling an exponential growth curve. The spikes correspond to the bladder contractions associated with the micturition reflex. The curve formed by the ...
Disorders of bladder function may be dealt with surgically, by redirecting the flow of urine or by replacement with an artificial urinary bladder. The volume of the bladder may be increased by bladder augmentation. An obstruction of the bladder neck may be severe enough to warrant surgery. Ultrasound can be used to estimate bladder volumes. [31 ...
In chronic retention, ultrasound of the bladder may show massive increase in bladder capacity (normal capacity is 400-600 ml). [citation needed] Non-neurogenic chronic urinary retention does not have a standardized definition; however, urine volumes >300mL can be used as an informal indicator. [7]
“Your kidneys make urine, and then (it’s) funneled down two tubes called ureters to the bladder. I’d say normal bladder capacity is about 400 to 600 (cubic centimeters).” ...

Urinalysis, a portmanteau of the words urine and analysis, [1] is a panel of medical tests that includes physical (macroscopic) examination of the urine, chemical evaluation using urine test strips, and microscopic examination.
The urine volume is measured (this shows how efficiently the bladder empties). High volumes (180 ml) may be associated with urinary tract infections. [5] A volume of greater than 50 ml in children has been described as constituting post-void residual urine. [6] High levels can be associated with overflow incontinence.
Overactive bladder affects approximately 11% of the population and more than 40% of people with overactive bladder have incontinence. [5] [6] Conversely, about 40% to 70% of urinary incontinence is due to overactive bladder. [7] Overactive bladder is not life-threatening, [1] but most people with the condition have problems for years. [1]
