What is Urodynamics Test?

Urinary incontinence poses serious social and medical problems in all societies, more in women.

The Urodynamics Test has a gold standard for revealing the causes of urinary incontinence problem.

Urodynamics Test provides detailed diagnostic examination of urinary retention and urination problems that can be seen in men and women of all ages. It is a test in which urinary disorders are detected by instant computer measurements.

Urodynamics is a painless measurement. It can be applied to all ages, including newborn babies. It does not require any preparation before the procedure. It is recommended to look for urinary tract infections before urodynamics testing. Calming drugs can be used in infants and young children.

The purpose of the urodynamics test is to measure the pressures inside the bladder and inside the abdomen while filling the bladder, to perform EMG for the nerves that provide bladder contractions, and to explain the cases of incontinence or urination by examining the bladder contraction pressures and electrical activity while urinating.

Who is Recommended for Urodynamics Test?

• Having urinary incontinence problems
• Difficulty while urinating
• Frequent urination
• Urine drip-drop
• Never feeling urine
• Urinary storage of urine less than it should be in the bladder

Urinary Mechanism

The bladder is in a form similar to a balloon with an elastic structure. Urine from the kidneys come to the bladder and accumulate. When the bladder reaches a certain fullness, an electrical signal is sent from the bladder to the brain and the feeling of urination is evoked.

When the feeling of urination comes, the brain orders to contract the bladder. The bladder contracts, and the sphincter mechanism is opened to prevent urine leakage at the exit of the bladder and urine flow is performed.

Urinary Disorders

• Bladder and brain problems (cerebrospinal diseases)
• Sagging of the bladder and the uterus
• Bladder contractions are more or less than normal
• Prostate or urinary tract stenosis
• The bladder is not empty enough

How is the test done?

In this test, a fine measuring catheter is placed in the bladder and a similar pressure measuring catheter into the makat. These two catheters allow calculating the pressures in the bladder. The catheter placed in the bladder pumps the water at the speed determined by the computer. The bladder is filled and the sphincter's electrical activities are measured. When the filling phase is over, the patient is asked to urinate. The flow rate is measured during urination. With all these data, information about the operation of the bladder and the problem of urination is obtained.
