Uroflowmetry: Free uroflowmetry measures how fast the patient can empty his/her bladder. Pressure uroflowmetry again measures the rate of voiding, but with simultaneous assessment of bladder and rectal pressures. It helps demonstrate the reasons for difficulty in voiding, for example bladder muscle weakness or obstruction of the bladder outflow.
The bladder will then be filled with saline and the patient's awareness of the event will be queried. The patient will often be asked to note when presence of liquid is felt, when the bladder feels full, and when the urgency to void is felt. The patient is then asked to void, and both flow and pressure are recorded. [5]
A sphygmomanometer (/ ˌ s f ɪ ɡ m oʊ m ə ˈ n ɒ m ɪ t ə r / SFIG-moh-mə-NO-mi-tər), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure.
Determination of how much urine is in the bladder, for example to assess for urinary retention. To look for evidence and the cause of chronic kidney disease, for example shrunken kidneys. [1] To assist with an interventional procedure, such as the taking of a biopsy, or draining of an abscess or cyst. [1] To monitor a kidney transplant. [1]
People who have high pressure bladders, meaning their bladder pressure increases significantly with small increments of fluid, are not good candidates for the procedure due to the risk of damage to the kidneys. [19] Also contraindicated are those who cannot hold large volumes of urine without refluxing into the kidneys. [3]
The key to recognizing abdominal compartment syndrome is the demonstration of elevated intra-abdominal pressure which is performed most often via the urinary bladder, and it is considered to be the "gold standard". The increased intra-abdominal pressure leads to compression of the renal veins, which, in turn, to an oliguria that is unresponsive ...
