Urodynamic Testing

Urodynamic testing is a diagnostic test to evaluate the bladder’s function and responsiveness for the emptying and storage of urine.


  • Bladder outlet obstruction
  • Incontinence
  • Incomplete emptying of the bladder
  • Voiding dysfunction
  • Neurologic conditions


The patient lies on his or her back on an exam table, and a bladder catheter is placed, in addition to a catheter placed in the rectum and several other sensors. These catheters are then attached to a specialized computer that measures the filling, storage, and emptying function of the bladder and the responsiveness of the bladder to certain stimuli.

Side Effects

Most patients will experience some slight burning with urination and/or pass a small amount of blood for the first 24 hours after the procedure. If the burning persists for longer than 24 hours, or if the patient has heavy bleeding or passage of clots, is unable to urinate and/or has a fever over 101 degrees, the patient should contact us.
