Question 5#

What filling speed is used during cystometry in neurogenic patients?

A. <10 mL/min
B. 10–30 mL/min
C. 30–50 mL/min
D. 50–100 mL/min
E. 100 mL/min

Correct Answer is A


Answer A

The filling rate during filling cystometry is important and determined by the patient undergoing urodynamic assessment (e.g., neuropathic versus non-neuropathic). Medium to fast fill during filling cystometry is described as 50–100 mL/min. In neuropathic bladders a slower fill of <20 mL/min is used. Fast filling in a neuropathic patient may lead to ‘artefactual’ detrusor contractions and reduced compliance.
