Review Functional assessment of the bladderJ Nordling. Ciba Found Symp. 1990. AbstractThe urinary bladder has two functions: to store and to empty. A frequency-volume chart completed by the patient provides useful information about voiding intervals, possible factors provocative for incontinence, functional bladder capacity and daily urine volume. Filling cystometry is used primarily to evaluate reflex function in the storage phase, giving information about the presence or absence of detrusor instability and (in combination with urethral EMG) about detrusor-sphincter coordination. Information is also obtained about bladder sensation, bladder capacity and bladder compliance. Detrusor function during emptying is closely related to outflow conditions and therefore demands simultaneous registration of detrusor pressure and urinary flow rate. An inverse relation exists between detrusor pressure and flow rate, which means that reduced flow rate causes increased detrusor pressure for the same detrusor power. Underactive detrusor function will result in low detrusor pressure and low flow rate. The finding of a non-contractile detrusor may indicate psychogenic inhibition or a neurogenic lesion. Sacral evoked potentials and denervation supersensitivity tests may help to distinguish between these conditions. Similar articles
Publication typesMeSH termsHow do you test your bladder?A cystometric test, or a cystometrogram, is a test that uses catheters to measure pressure inside your bladder. The test can tell how much the bladder can hold, how elastic your bladder is and when you feel the need to urinate.
How is bladder compliance measured?Bladder compliance is calculated by dividing the volume change by the change in detrusor pressure. Normal bladder compliance is defined as a value of >40 mL/cmH2O, with values of <13 mL/cmH2O representing severe compromise of bladder compliance (3).
Which retrograde procedure involves the examination of ureters and renal Pelviss?During a cystoscopy, a cystoscope is inserted through the urethra into the bladder. During a ureteroscopy, the urologist will focus on viewing the ureter and lining of the kidney, known as the renal pelvis.
What is Vesical pressure?Intravesical pressure (Pves): The pressure recording from a urodynamic catheter placed inside the bladder. Physiologic filling rate: A filling rate (during cystometry) that is less than the predicted maximum (see definition below).
