Urodynamics are a series of tests that thoroughly examine how your bladder works, both at rest and with activities such as coughing and increased abdominal pressure.
Tests may include
- Having a doctor or nurse observe your urination process, or having you urinate into a toilet with a scale and collection device
- Cystometry: Monitoring bladder pressure and behavior during filling with a special catheter
- Electromyography: Measuring nerve and muscle activity with sensors placed around or inside the urethra
- Video urodynamics (cystourethrogram): Using ultrasound to let your doctor see the lower urinary system
After the tests
- You may feel discomfort for a few hours after the tests, but your doctor will usually recommend drinking lots of water, taking a warm bath, or using a warm compress.
- You may need to take antibiotics for a few days to prevent infection.
