urodynamics
Pronunciation: YUR-oh-dy-NAM-iks
Diagnostic tests that measure bladder and urethral function during filling and voiding.
Full Definition
Urodynamics encompasses a series of tests designed to evaluate the function of the bladder, urethra, and urinary sphincters. These studies measure pressures, flow rates, and volumes to assess how well the urinary system stores and releases urine. Common urodynamic tests include cystometry, uroflowmetry, and pressure-flow studies. The results help diagnose conditions such as overactive bladder, neurogenic bladder dysfunction, bladder outlet obstruction, and stress incontinence. Urodynamic studies are essential for surgical planning and monitoring treatment outcomes in complex urologic conditions.
