Current concepts and controversies in urodynamics.
Urodynamics is the dynamic study of the transport, storage, and evacuation of urine by the urinary tract. It is comprised of several tests that, when used individually or collectively, can give information about lower urinary tract function. The components of the urodynamic study are uroflowmetry, cystometry, pressure-flow studies, electromyography, urethral pressure profilometry, leak point pressure measurement, videourodynamics, and ambulatory urodynamics. Familiarity with the recent advances and controversies of each component is essential when using urodynamics to diagnose and treat lower urinary tract dysfunction.
