Videourodynamic evaluation that incorporates radiographic imaging with
simultaneous measurement of bladder and urethral pressure is the most
precise method available for diagnosing complex incontinence and void
ing disorders. In addition, videourodynamics has been instrumental to
the development of our present knowledge about urethral and bladder fu
nction including the concepts of detrusor and abdominal leak point pre
ssures. Although these studies are more expensive and time consuming,
the authors have found videourodynamic evaluation indispensable when t
he diagnosis remains in question after simple urodynamics and when the
studies and clinical scenario do not agree.
