URODYNAMICS TESTING THE FIRST STEP TO A SOLUTION

The first step in solving a problem is to accurately define it. This is especially true in treating bladder dysfunction. The initial assessment is based on patient history and an examination, but only Urodynamics testing provides the data necessary to establish the accurate diagnosis needed to determine the appropriate kind of treatment.

Urodynamics testing is simple, virtually painless, and can be performed easily in an office setting. The complete evaluation requires approximately 1 to 1 and 1/2 hours. Occasionally, a patient will have to return for a repeat test if conflicting data is obtained. Patients may find this type of testing somewhat awkward or embarrassing - after all, urination is a subject usually confined to the privacy of a bathroom. The doctor and any staff in attendance during the testing will do everything possible to put the patient at ease.

Patient, doctor, and staff have the same goal: to find the cause of any urinary tract problem and to solve those problems with the best available treatment.

The testing determines how well the bladder is functioning, and measures the ability to retain and expel urine. Uroflow testing records a graph reflecting the cc’s per second of urine voided. Urodynamics also involves evaluation and inspection of the tube through which the urine leaves the body (urethra). This examination allows the doctor to look at the valve, which connects the urethra to the bladder, and is useful in diagnosing bladder spasms and other disorders. Abnormal bladder function (including involuntary loss of urine, inability to retain urine in a full bladder, unexplained urge to void, frequent urination, getting up at night to void, as well as a weak urine stream) and retention and overflow incontinence are usually readily diagnosed following these tests.

Patients are asked to arrive at the office with a full bladder to expedite the testing procedures. At the beginning of the test you may be asked to urinate in a receptacle. The time and effort needed to start the flow; the continuity of the urine stream, and the presence of dribbling after finishing will be noted.

Then, you will be asked to lie on your back on an examining table. The opening of the urethra will be thoroughly cleansed. A well-lubricated, thin, flexible tube (catheter) will be gently inserted into the urethra and slowly advanced to the bladder. Any urine remaining in your bladder (residual volume) will be measured.

A measured volume of sterile water is then instilled through the catheter into your bladder. The catheter is attached to a device, which measures the pressure in the bladder during the installation. You may be asked to report any sensations such as bladder fullness, or the urge to urinate.

The process may be repeated. Each time the bladder is filled you will be asked to report your first urge to urinate. When your bladder reaches its full capacity you will be asked to void. If you have difficulty doing so while lying down you may be asked to stand or sit to void.

To test for stress incontinence the catheter may be withdrawn while the bladder is full and you may be asked to cough, bend over, and /or lift a heavy object. With stress incontinence these actions may cause leakage of urine.

In all cases, a urine culture will be done to check for any evidence of bacterial infection.

Female urinary tract problems are extremely common and can usually be treated once the cause is determined. Urodynamics testing can be the first step in solving these frustrating and inconvenient conditions.
