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.
排尿期膀胱尿道静压剖面图是一种记录与膀胱相邻的连续尿道节段排尿压力静态（横向）成分的方法，它使我们能够直接确定16名男性膀胱出口梗阻的部位和程度。通过将这种技术与10F三腔导管结合尿流率测定和放射学研究，对孤立性膀胱颈梗阻的诊断更有信心。使用5F单腔导管进行的重复研究表明，用10F导管识别出的梗阻并非完全是人为造成的。我们在几名非神经源性膀胱颈梗阻男性中使用这种技术的经验表明，将这项研究纳入尿动力学检查手段很重要。
