ABSTRACT
Urodynamics (UDS) is the umbrella term for any test giving a dynamic evaluation of lower urinary tract (LUT) function. The test in most widespread use is cystometry, in which abdominal and bladder pressure are measured synchronously with urine flow during bladder filling (filling cystometry) and voiding (pressure flow studies), as described in chapter 32. Conventional uds is informative in well-defined circumstances, but many women have additional complications in their symptomatology or past medical history. This can make the ability to obtain extra information important for full insight into underlying pathophysiology and consequently for making safe treatment recommendations.
