Urodynamics

Question 1

Urodynamic tests

Answer 1

techniques which measure the bladder, sphincters & uretha and how well they are at storing and releasing urine

Question 2

What can urodynamics find?

Answer 2

They can show whether the bladder is having involuntary contractions, causing urine to leak

Question 3

Cystometry

Answer 3

measures how much urine the bladder can hold and the pressure in the bladder. Can be used to diagnose overactive bladders and incontinence.

Question 4

Uroflowmetry

Answer 4

A test which measures how much and how fast urine leaves the bladder. It’s measured in two parts:
measures average rate of flow
measures top rate of flow
Can be used to show blockages (e.g. enlarged prostate)

Question 5

Voiding pressure study

Answer 5

A catheter and manometer are used to measure the pressure in the bladder when urinating & the urine flow rate. This can help to find a blockage in the bladder (from prostate enlargement).

Question 6

Limitations of voiding pressure studies

Answer 6

Pain
burning sensation
blood in the urine
