To achieve a comprehensive urodynamics assessment, we perform a number of tests simultaneously, which allows us to determine the status of the kidneys, bladder and urethra. Together these tests provide valuable information about bladder capacity, voiding and bladder pressure.

Uroflow with and without EMG

This study evaluates the volume and rate of urine flow per second in accordance with established norms. After completion, we perform an ultrasound of the bladder right in the unit to determine if the child is fully emptying their bladder. This is a completely non-invasive study.

This study is performed to allow us to evaluate:

  • Stability of the bladder
  • Peak urinary flow
  • Bladder capacity
  • Ability to empty the bladder

The EMG allows us to monitor pelvic floor muscle activity while voiding.

Simple Urodynamics

This study allows us to evaluate all of the above along with:

  • How much pressure builds in the bladder as it fills
  • Whether the bladder is having involuntary contractions or is contracting normally
  • How full the bladder is when there is an urge to void


This study allows us to integrate imaging technology with simple urodnyamics to determine if there are any anatomic abnormalities in the bladder and urethra. This study is accomplished by adding contrast fluid to the fluid filling the bladder in order to image the shape of the bladder and urethra while the bladder is filling, having contractions and voiding. This study can also help us determine if there are any other anatomic considerations like vesicoureteral reflux (VUR) or diverticula.
