CMG / Urodynamics Testing
Otherwise known as a cystometrogram (CMG), urodynamics are invaluable in understanding how a person’s bladder functions. These tests measure bladder pressure when at rest and when filling.
A technician inserts a catheter into the urethra and bladder to fill the bladder with water. A monitor measures and records the pressure within the bladder. This test helps measure bladder strength and function as well as urinary sphincter health. Most urodynamic testing focuses on the bladder’s ability to empty steadily and completely. It can also show whether or not the bladder is having abnormal contractions, which can cause leakage. Your doctor supervises the test and will review the results with you once it is complete.
After this test, one may experience mild discomfort or urinary frequency for a few hours. Drinking two 16 ounces of water each hour for two hours should help.
