  2. Bladder - Wikipedia

    en.wikipedia.org/wiki/Bladder

    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 ...

  3. Urinary retention - Wikipedia

    en.wikipedia.org/wiki/Urinary_retention

    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]

  4. Cystometry - Wikipedia

    en.wikipedia.org/wiki/Cystometry

    Cystometry, also known as flow cystometry, is a clinical diagnostic procedure used to evaluate bladder function. Specifically, it measures contractile force of the bladder when voiding . The resulting chart generated from cystometric analysis is known as a cystometrogram (CMG), which plots intravesical pressure against the volume of fluid in ...

  5. Urinary system - Wikipedia

    en.wikipedia.org/wiki/Urinary_system

    The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.

  6. Urination - Wikipedia

    en.wikipedia.org/wiki/Urination

    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).

  7. Urodynamic testing - Wikipedia

    en.wikipedia.org/wiki/Urodynamic_testing

    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.

  8. Overactive bladder - Wikipedia

    en.wikipedia.org/wiki/Overactive_bladder

    [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.

  9. Nocturnal enuresis - Wikipedia

    en.wikipedia.org/wiki/Nocturnal_enuresis

    The etiology of NE is not fully understood, although there are three common causes: excessive urine volume, poor sleep arousal, and bladder contractions. Differentiation of cause is mainly based on patient history and fluid charts completed by the parent or carer to inform management options. [28] [29] Bedwetting has a strong genetic component.
