Urodynamic Study

Description:
A urodynamic study is a series of tests that gives your doctor a detailed look at the function of your bladder and urethera. These tests can help your doctor evaluate any problems you may be having with storing urine or voiding (eliminating) urine from your body.

The tests are generally painless, so you don't need sedating medication. A catheter (soft, hollow tube) will with a special sensor will be placed in your urethera and a second catheter in your vagina or rectum.

Tests:
There are 5 small tests that complete the urodynamic study.

• Cystometry: This test evalutates how much the bladder can hold, how strong the bladder muscle is, and how well the signals work that tell you when your bladder is full. Through a catheter, your bladder is filled with sterile water or saline solution. You're asked to report any sensations you feel and whether they're similar to symptoms you've felt at home. You may be asked to cough, stand and walk, or bear down during this test.
• Electromyogram: This test helps to evaluate the muscle contractions that control urination. Electrode wires may be placed near the rectum or urethra to make the recording. You may be asked to tighten or relax your sphincter muscles during this test.
• Urethral Pressure Profile: This test measures pressure in the urethra and bladder. It measures this pressure both while you are relaxed and when pressure is applied. You may be asked to cough or perform other measures to exert pressure with the abdomen.
• Pressure Flow Study: This test measures the pressure and flow of urine out of your bladder. It is often performed after cystometry. You are asked to urinate while a catheter with sensors in the urethera measures the pressures.
• Uroflowmetry: This test measures the amount and speed of urine you void from your bladder. You urinate into a funnel attached to a computer that records your urine flow over time. The ammount of urine left in your bladder after you void may also be measured immediately after this test.

Time:
These tests take an hour or more.

Preparation:
Do not apply lotion to your legs prior to this test. Wear two peice clothing that is slacks or a shirt and a top.

After the Test:
When the study is finished, you'll get dressed and return to the consultation room. Test results may be available soon after the stusy is finished, or you may return to the office in a few days for results. The report may include a summary of the study results, the diagnosis and suggestions for further evaluation or treatment. Your doctor can talk with you about the study report and your options.
