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.
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]
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 pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and anal canal. In females, the uterus, fallopian tubes, ovaries and upper vagina occupy the area between the other viscera. [1] [2]
Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as: Urodynamic tests can help explain symptoms such as:
The urethra of an adult human female is 3-4 cm long. [4] The female urethra is located between the bladder neck to the external urethral orifice and is behind the symphysis pubis. [4] The urethral wall is composed of an inner epithelial lining, a sub-mucosa layer containing vascular supply, a thin fascial layer, and two layers of smooth muscle. [4]
