Y1 - 2020 N1 - T2 - Smith & Tanagho's General Urology, 19e AB - Urodynamics (UDS) is an interactive study of the lower urinary tract (LUT) that evaluates the transport, storage, and evacuation of urine. UDS is composed of a combination of tests that can be used collectively to obtain functional information about the LUT. The study can be divided up into two main phases: the storage (or filling) phase and the emptying (or voiding) phase. During the storage phase, cystometry is performed and includes measurement of bladder sensation, contractions, compliance, and capacity. Other tests, such as abdominal leak point pressure (ALPP) and detrusor leak point pressure (DLPP), can also be performed when indicated. The emptying phase consists of pressure flow studies and can give valuable information about voiding.
