Urodynamics testing is used to assess the lower urinary tract and is performed prior to planning surgery for urinary leakage or if the cause of leakage is not clear. It assesses how much urine your bladder can hold, what makes you leak (cough, valsalva, jumping, ect.), and assesses for problems emptying the bladder. You will be asked to come to your appointment with a full bladder. First you will be asked to empty your bladder at the bedside commode to measure your urine, next a small catheter will be used to measure your post-void residual (how much urine is left in your bladder after voiding). The pressure sensitive catheter used for urodynamic testing will then be placed in your bladder and one in your vagina, – your bladder will be filled with saline, and you will be asked to cough and bear down at various time during the test. The test is performed in the office and will take approximately 45 minutes to one hour. Please call the Woman’s Clinic if you have further questions regarding the test.
