目标.研究导管对充盈感觉的影响。在我们以前的研究中，我们证明了一些患者在膀胱测压时尽管缺乏充盈，但仍能感知到感觉。该研究包括45例下尿路症状归因于良性前列腺增生。患者平均年龄为57.9岁（范围48 - 79岁）。病人被遮盖起来，以防止他们看到自己的阴茎和填充袋，泵和屏幕的过程。在第一阶段，导管被固定在阴茎皮肤上，而不是通过尿道引入，病人被告知测试已经开始。在第一阶段结束时，排空膀胱。在第二阶段之前，引入了8 F尿动力学导管，但在测试期间，没有输注任何东西。在第三阶段期间，以50 mL/min的泵速进行充盈性膀胱测压。在所有三个阶段后排空膀胱。每种感觉被感知的时间（以秒为单位）被用来比较感觉。在第一阶段，21例患者报告了第一感觉，10例报告了第一欲望，4例报告了正常的欲望，尽管缺乏导管插入术。在3个阶段感觉到的患者的平均第一感觉/第一欲望、第一感觉/正常欲望、第一欲望/正常欲望比值与第二和第三阶段感觉到的患者的强烈欲望/正常欲望比值之间差异均无统计学意义（均P > 0. 05）。尽管在第一和第二阶段报告了感知，但导管不可能是主观性的唯一原因。
Objectives. To investigate the impact of the catheter on perceptions of filling. In our previous study, we demonstrated that some patients perceived sensations despite a lack of filling during cystometry.Methods. The study included 45 patients with lower urinary tract symptoms attributed to benign prostatic hyperplasia. The average patient age was 57.9 years (range 48 to 79). Patients were draped to keep them from seeing their penis and the filling bag, pump, and screen process. In the first phase, the catheter was fixed to the penile skin without introducing it through the urethra, and the patient was told the test had begun. At the end of the first phase, the bladder was emptied. Before the second phase, an 8F urodynamic catheter was introduced, but during the test, nothing was infused. During the third phase, filling cystometry was performed with a 50-mL/min pump speed. The bladder was emptied after all three phases. The times that elapsed until each sensation was perceived, in seconds, were used to compare the sensations.Results. In the first phase, 2 1 patients reported a first sensation, 10 reported first desire, and 4 reported normal desire, despite a lack of catheterization. No statistically significant difference was found between the mean first sensation/first desire, first sensation/normal desire, first desire/normal desire ratios of the patients who perceived sensations in the three phases and the strong desire/normal desire ratios of the patients in the second and third phases (P > 0.05 for all).Conclusions. Although the perceptions were reported in the first and second phases, the catheter could not be the sole cause of the subjectivity.
