Urodynamic Testing (Urodynamics)

Urodynamic testing is a procedure which tests the functionality of bladder, sphincter, and urethra especially focusing on how well these organs can store and release urine.

Urodynamic testing mostly focuses on the bladder and its ability to store and release urine and in some cases looks for any problems which may lead to urine leakage. An urodynamic test is recommended if any symptoms of the lower urinary tract such as urine leakage, frequent urination, painful urination and recurrent urinary tract infections are detected.

Urodynamic tests vary from a simple observation to precise measurements which require complex instruments and include:

  • Uroflowmetry: is used to measure the speed and volume of urine.
  • Cystometric test: focuses on the capacity of the bladder for holding urine and also when the urge to urinate begins relative to bladder fullness.
  • Post void residual measurement: is used to measure the amount of urine left after urination in the bladder. In this measurement harmless sound waves from ultrasound equipment is used for imaging the bladder.
  • Video urodynamic tests

The availability of results after urodynamic tests depends on the complexity of the tests. For instance, results of cystometry, which is a simple test, are available immediately after the test. On the other hand, results of more complex tests such as video urodynamic tests may take up to a few days.

If this problem remains untreated there might result in frequent urinary tract infections or in severe cases, damaging the functionality of kidney in the patient.

This problem can be treated by one or more of the following options:

  • Antibiotics or antiseptics: may be used in case of any infection or surgery in case of severe disorders.
  • Clean intermittent self catheterisation (CISC): is another treatment option which enables patients to efficiently empty the bladder. In this procedure, patients are required to insert a urinary catheter under clean conditions at regular intervals.
