urodynamics
Diagnostic testing that evaluates bladder and urethral function during filling and emptying.
Full Definition
Urodynamics encompasses a series of tests designed to assess lower urinary tract function, including bladder sensation, capacity, compliance, and contractility, as well as urethral function and coordination. The study typically involves cystometry, pressure-flow studies, and electromyography of pelvic floor muscles. In pediatric patients, these studies are crucial for evaluating conditions such as neurogenic bladder, dysfunctional voiding, and treatment outcomes. Results guide medical and surgical management decisions and help monitor treatment effectiveness over time.
Usage
Usage note: Often abbreviated as UDS; specify components performed (cystometry, EMG, pressure-flow).
