Chapter 253 Urodynamic Testing: Simple

DESCRIPTION

Simple urodynamic testing involves measurement of bladder function carried out with the use of simple equipment readily found in the office setting.

INDICATIONS

Urinary incontinence (stress, urge, mixed, overflow). May be used as an adjunct to the evaluation of interstitial cystitis or other urinary complaints.

CONTRAINDICATIONS

Active bladder infection. Known or suspected allergy to cleansing solutions or local anesthetics to be used.

REQUIRED EQUIPMENT

• Sterile gloves, antiseptic solution and sterile cotton balls, or skin preparation swabs
• Sterile urine specimen cup (with graduations)
• 12- or 14-French straight catheter
• Large catheter-tip syringe (without piston) or “Asepto” surgical irrigation syringe (without bulb)
• 1 liter of sterile water or saline (intravenous fluid without glucose will do) at room temperature
• Intravenous tubing and measuring tape or ruler, or spinal manometer
• Commode or toilet
• Stopwatch or watch that allows counting of seconds
• Absorbent underpads
• 2% lidocaine jelly in mushroom-tipped syringe (optional)
• An assistant is advantageous

TECHNIQUE

Immediately before the procedure is started, the patient is asked to empty her bladder (in private and in her usual manner). The patient is placed in the dorsal lithotomy position, and the external urinary meatus and surrounding vulvar vestibule are cleansed with antiseptic solution. One to three milliliters of topical anesthetic, such as 2% lidocaine, are introduced into the urethra.
