DESCRIPTION
Urodynamics is an in depth evaluation of the function of the lower urinary tract (bladder and bladder outlet or urethra). These studies are important in diagnosing problems of loss of urinary control, urinary retention (inability to pass urine) or frequency of urination. This evaluation involves placing small tubes through the urethra into the bladder to measure the pressure inside the bladder. In many instances, a small tube is also placed inside the rectum to measure the pressure in the abdomen. This study usually includes a cystoscopy. Cystoscopy is the visual inspection of the bladder and urethra with a special telescope-like instrument. A local anesthetic jelly (no injections necessary) is used for urodynamics and cystoscopy. Occasionally X-rays may be taken during the study. A complete evaluation may take up to two hours. Please ask us if you have questions.

POSSIBLE RISKS
A small risk of infection exists after this type of procedure. If new symptoms of burning, frequency or bleeding occur afterwards, please let us know. If X-rays are used, you will receive a small amount of radiation. Tell us before the procedure if you might be pregnant.

PREPARATION
Try to report for your evaluation with a comfortably full bladder. If you empty your bladder just prior to your appointment it may delay your test. If you have been taking medication specifically to help your bladder relax or work better in any way ask us if you should stop taking it five days before the evaluation. Examples of medications that should be stopped are ditropan (oxybutinin), probanthine (propantheline), tofranil (imipramine), urispas, cystospaz, Cardura, Hytrin. If you are taking antibiotics for a bladder or kidney infection, continue taking that medication.
