Peritron+ is a new handheld device, which can be attached to a urethral catheter to measure intravesical pressures (Pves). The goal of this study was to assess if Pves recorded by standard urodynamics (UDs) are comparable to those recorded by the Peritron+.
Patients with voiding dysfunction and an indication for UD underwent measurement of Pves with nonvideo UD and Peritron+. Pves were recorded at volumes of 50, 100, and 200 mL for the supine and sitting positions. A failure of the Peritron+ was considered to be a discrepancy of Pves values >3 cmH O between Peritron+ and UD recordings. Two-way ANOVA was used to assess for statistical significance. P-values < 0.05 were considered significant.
Ten female patients, mean age 51 years old, were enrolled in the study. The difference in Pves measurements between Peritron+ and UD were ≤3 cmH O at all bladder volumes measured in a supine and sitting positions. There were no adverse events and there were no malfunctions of the Peritron+ device during the study.
Peritron+ handheld device accurately assessed Pves at different intravesical volumes when compared to UD measurements. The Peritron+ is a simple and safe device, which can be used in the office by a clinician and at home by a patient to monitor Pves and help to select patients who may require standard UD re-evaluation. This will be a valuable tool in managing patients with neurogenic and nonneurogenic bladders who are at a risk of upper urinary tract deterioration.
Peritron+ 是一种新型手持设备，可连接到尿道导管以测量膀胱内压（Pves）。本研究的目的是评估标准尿动力学（UD）记录的 Pves 是否与 Peritron+ 记录的 Pves 相匹配。
患有排尿功能障碍且需要进行 UD 的患者接受非视频 UD 和 Peritron+ 测量 Pves。在仰卧位和坐位时，以 50、100 和 200ml 的容量记录 Pves。当 Peritron+ 和 UD 记录的 Pves 值差值 >3cmH2O 时，认为 Peritron+ 失败。使用双向方差分析评估统计学意义。P 值<0.05 被认为具有统计学意义。
10 名女性患者，平均年龄 51 岁，入组本研究。在仰卧位和坐位测量的所有膀胱容量下，Peritron+ 和 UD 测量的 Pves 差值均≤3cmH2O。在研究期间，没有发生不良事件，也没有出现 Peritron+ 设备故障。
与 UD 测量相比，Peritron+ 手持设备在不同膀胱容量下准确评估了 Pves。Peritron+ 是一种简单且安全的设备，可由临床医生在办公室使用，也可由患者在家中使用，以监测 Pves 并帮助选择可能需要重新进行标准 UD 评估的患者。这将是管理有发生上尿路恶化风险的神经源性和非神经源性膀胱患者的有价值的工具。
