Using a tri-lumen graduated 10F catheter we attempted to record static (lateral) pressures at successive points in the urethra, synchronous with intravesical pressure recorded during voiding. Based on our understanding of the essential physical principles described by many earlier investigators we attempted numerous studies in a predominantly male population, which included normal male and female subjects, and male subjects with bladder outlet obstruction of varied etiology. We also attempted to evaluate the effects of the Valsalva maneuver, augmenting the detrusor contraction and artificial distal obstruction (penile compression) on the micturitional static urethral pressure profiles. Studies also were performed to compare the static urethral pressure profiles obtained with the anterograde (catheter withdrawal) and with the retrograde (catheter insertion during voiding) techniques. All of these studies have helped in understanding the various factors, such as double obstructions, artifactual catheter obstructions and incompetent distal sphincter mechanisms, in the interpretation of the micturitional static urethral pressure profile.
我们使用一根三腔、刻度为10F的导管，尝试在尿道的连续点记录静态（侧向）压力，同时记录排尿期间膀胱内压力。基于我们对许多早期研究者所描述的基本物理原理的理解，我们在以男性为主的人群中进行了大量研究，其中包括正常男性和女性受试者，以及病因各异的膀胱出口梗阻男性受试者。我们还试图评估瓦尔萨尔瓦动作、增强逼尿肌收缩和人为远端梗阻（阴茎压迫）对排尿静态尿道压力曲线的影响。还进行了研究，以比较顺行（导管回撤）和逆行（排尿期间插入导管）技术获得的静态尿道压力曲线。所有这些研究都有助于理解在解释排尿静态尿道压力曲线时的各种因素，如双重梗阻、人为导管梗阻和远端括约肌机制功能不全。
