Urodynamics involve placing a very small catheter into the bladder to measure bladder function. It is a two-phase test performed with the same catheter and usually takes 10-20 minutes. During the first phase, the bladder is filled with water through the catheter to measure the capacity and elasticity of the bladder and to check for any bladder spasms. During the second phase, patients void around the catheter while it remains in the bladder. This phase measures how effectively the bladder empties. Urodynamics are used to evaluate patients with incontinence, patients with the inability to void, and, at times, patients with prostate obstruction.
