Urodynamic Bladder Testing in Waconia, MN

Urodynamic studies are performed to evaluate and help diagnose bladder problems. Urodynamic testing aims to analyze how well the bladder, sphincters, and urethra are able to function when it comes to holding and releasing urine.

Symptoms That Call for Urodynamic Testing

Typically, our physicians may recommend urodynamic testing for individuals who experience bladder problems such as involuntary leakage of urine, or even total loss of bladder control. Urodynamic testing may be offered when initial treatments have not worked. Other common urinary problems that may be an indication for Urodynamics include:

  • Frequent urination, particularly during nighttime hours
  • Difficulty in emptying the bladder
  • Repeated urinary tract infections
  • Sudden and intense urges to urinate
  • Pain during urination
  • Issues in starting or stopping the flow of your urine

Types of Urodynamic Testing at Western OB/GYN

All of the following components of Urodynamic testing, if needed, are performed at one visit.

Cystometrogram (CMG)

In order to test the bladder and its capacity, a cystometrogram will likely be performed. The brain and bladder work together normally to store and release urine.This process must be coordinated to have normal bladder function. A cystometrogram can help determine abnormalities of this system. The cystometrogram includes the following 2 tests:

1. Pressure Flow Study

This test analyzes how hard the bladder must work to create enough pressure to empty the bladder (flow of urine).

2. Leak Point Measurement

With a set amount of fluid in the bladder, this measurement determines how well the urethra can hold urine in the bladder.


As its name suggests, uroflowmetry measures the flow of a person’s urine. The two primary measurements from this test are the total volume voided and the speed at which the individual is able to void. Abnormal results will often alert the physician to an issue of weakened muscles or blocked urine flow.

Electromyogram (EMG)

If the physician suspects that an individual’s symptoms may be caused by a dysfunction of the nerves or muscles of the urinary system, an electromyogram may performed. Done simultaneously with the cystometrogram, the test uses sensors on the skin to measure the sphincter activity and how well they respond to the person’s bodily commands.

Results and Follow-Up Treatments

Most urodynamic tests will be concluded after approximately 30 minutes depending upon the particular test being performed, and your physician will often consult with you afterward to discuss the outcome of your assessment.

The goal of urodynamic testing is to help determine a definitive cause of the person’s bladder problems. Once a source of the person’s symptoms has been identified, her physician can offer individualized recommendations and treatment options.
