Preparation for urodynamic testing
What is a urodynamic testing?
A full urodynamics procedure is a series of tests done to find out how well your child’s bladder is working. It provides information how much urine the bladder can hold, its sensitivity, expansion capacity, intravesical pressure in filling and voiding phases, urine flow, post void residual urine and outer urethral sphincter activity.
The examination begins with urination into a special vessel followed by the introduction of a small catheter into the bladder under a local anesthetic.
PREPARATION OF THE CHILD

- in the evening preceding the examination give your child a glycerine suppository for defecation
- the child should come to the facility with a full bladder
