Urodynamic Testing (UDT)

What is an urodynamic test (UDT)?

An UDT is a series of tests that gives Dr. Hardy a detailed look at the function of your bladder and urethra. These tests can help evaluate any problems you may be having with storing urine or eliminating urine from your body.

Why would I need this procedure?

There are several reasons that Dr. Hardy would like to perform this procedure and they are:

  • leaking of urine with coughing, sneezing or exercise.
  • frequent urination throughout the day
  • frequent urination throughout the night
  • strong urgency, hesitancy with urinating
  • pain with a full bldder

What can I expect before the procedure?

Any two days before the procedure, you will be asked to complete a two-day diary (UROLOG) of your urination habits. The urolog can be a very helpful part of your evaluation. To complete the urolog, you will be given a "hat", which fits inside the toilet, to measure your urine. On the urolog, you will need to record the time and amount that you drink (intake) as well as the time and amount that you urinate (output). The third column is for any symptoms that you may have. For example, leaked urine, urgency, hesitancy, burning, etc. Record the volume using the "ml" measurement.

What can I expect during the procedure?

This procedure is done in our CHESAPEAKEoffice. You will be in our office for 30 minutes. A small, flexible catheter with a sensor will be placed in you urethra (the canal that carries urine from the bladder out of the body). The catheter is connected to our urodynamic machine which will print out a graph during the study. The bladder will be filled with sterile water to stimulate the bladder filling and a full bladder. You may be asked to cough, stand, and bear down during the study.

What complications could occur?

Some possible complications that may occur are:

  • Urinary tract infection
  • Irritation in the urethra from the catheter

You will be given a prescription for a 3 day course of antibiotic to prevent any bladder infections as well a prescription for Pyridium, which is an analgesic to take any irritation away.
