Urodynamic testing (UDS) is an office based diagnostic sophisticated study used to help identify various bladder disorders. It is defined as a set of tests used to measure lower urinary tract function. It entails placing a catheter in the urethra that has the ability to measure pressures within the bladder. The multi-channel pressure study is associated with minimal discomfort and takes approximately 30 minutes to perform. The study allows us to diagnose “over” and “under” active bladders as well as a “weak” or “spastic” urinary sphincter. Results allow the urologist to select the appropriate treatment such as surgery or certain medications to alleviate problems with bladder control or ability to empty.
