A Simple CMG allows us to assess how your bladder and sphincter behave while you store urine and when you pass urine, and to assess if you have hidden stress urinary incontinence. This test is done for people with advanced vaginal prolapse and people with neurologic disease that can affect bladder function.
This test will measure your bladder capacity and pressure. By doing this, we can identify problems such as small capacity bladder, overactive bladder, or high-pressure bladder.
A Simple CMG test takes about 15-20 minutes. You will be positioned on an exam table lying on your back. If you have a wheelchair that reclines, the study can be performed while you remain in your wheelchair. Your urethral opening will be cleansed with Betadine® to eliminate any bacteria on the surface. A catheter will be inserted into your urethra and advanced into the bladder. The bladder will be filled with saline solution and filling pressures will be recorded. We will ask you to report any sensations that you might have, such as coolness from the saline fluid, fullness, the need to urinate, urgency, pain, etc. You may experience some urine leakage during the study. Should this occur, there is no need to be embarrassed, as we expect this may happen during the test. If you do have leakage, let the technician who is administering the test know this.
You may experience a sense of burning or pressure when the catheter is inserted into the urethra. Also, it is normal to have some irritation when you urinate for 24-48 hours following the study. You may note a small amount of blood in the urine. You will be given an antibiotic after the procedure to guard against infection.
We will ask you to empty your bladder at the end of the test. Measuring the bladder pressure during urination will help us identify the problem so that we can prescribe treatment.
You needn’t do anything special to prepare for this study. You can eat and drink as you normally would before you arrive to the clinic. The test is done in the clinic and does not require sedation or anesthesia. You may resume your usual daily activities immediately following the Simple CMG.
Call the clinic’s nurse if you develop a fever of 100.5 degrees Fahrenheit or higher, have chills, persistent bleeding, or cannot urinate.
Neuromodulation is a clinically proven, FDA approved (since 1997) therapy for management of Refractory OAB (Overactive Bladder), Incomplete Bladder Emptying (not due to outflow obstruction), and Fecal Incontinence (the latest since March 2011).
