Videourodynamic studies.

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 voiding disorders. In addition, videourodynamics has been instrumental to the development of our present knowledge about urethral and bladder function including the concepts of detrusor and abdominal leak point pressures. Although these studies are more expensive and time consuming, the authors have found videourodynamic evaluation indispensable when the diagnosis remains in question after simple urodynamics and when the studies and clinical scenario do not agree.
