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.

A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for recurring urinary tract infections. [citation needed] In adults older than 60 years, 50-100 ml of residual urine may remain after each voiding because of the decreased contractility of the detrusor muscle. [7]
Average urine production in adult humans is around 1.4 L (0.31 imp gal; 0.37 US gal) of urine per person per day with a normal range of 0.6 to 2.6 L (0.13 to 0.57 imp gal; 0.16 to 0.69 US gal) per person per day, produced in around 6 to 8 urinations per day depending on state of hydration, activity level, environmental factors, weight, and the ...
The ability to voluntarily inhibit micturition develops by the age of two–three years, as control at higher levels of the central nervous system develops. In the adult, the volume of urine in the bladder that normally initiates a reflex contraction is about 300–400 millilitres (11–14 imp fl oz; 10–14 US fl oz).

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 ...
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.
[1] [20] Additionally, urine culture may be done to rule out infection. The frequency/volume chart may be maintained and cystourethroscopy may be done to exclude tumor and kidney stones. If there is an underlying metabolic or pathologic condition that explains the symptoms, the symptoms may be considered part of that disease and not OAB.
