title: Urodynamic localization of isolated bladder neck obstruction in men: studies with micturitional vesicourethral static pressure profile.
abstract: Micturitional vesicourethral static pressure profile, a method of recording the static (lateral) component of voiding pressure in the successive urethral segments contiguous with the bladder, has allowed us to establish directly the site and degree of bladder outlet obstruction in 16 men. The diagnosis of isolated bladder neck obstruction was confirmed with greater confidence by using this technique with a 10F trilumen catheter in conjunction with uroflowmetry and radiologic studies. Repeat studies with a 5F single lumen catheter have suggested that the obstructions recognized with the 10F catheter ware not entirely artifactual. Our experience with this technique in several men with non-neurogenic bladder neck obstruction indicates the importance of including this study in the urodynamic armamentarium.
