Abstract

Objectives

To evaluate the effectiveness of a novel portable urine flowmeter, Freeflow, for examining the actual state of urination at home.

Methods

Forty-three patients with benign prostatic hyperplasia used the Freeflow uroflowmeter in the hospital and at home without accumulating urine. We created a nomogram for each patient's urine volume and maximal urinary flow rate (Qmax). Furthermore, we investigated the actual state of each patient's urination. We also investigated the differences in the micturition status between daytime and nighttime.

Results

Of the 43 patients, 40 were able to provide the necessary data in the hospital, and all patients provided data measured at home. The trial period of the home assessment was 2-7 days. Regarding the average urine volume, no significant difference was observed between in-hospital and at-home patients; however, Qmax and mean flow rate (Qave) were significantly higher at home. The average coefficient of variation was very large. The relationship between daytime and nighttime was observed in 30 patients; urine volume increased significantly at nighttime; however, no significant difference was observed in Qmax and Qave. The nomogram for several days and a completed urinary diary helped to display daytime and nighttime urination characteristics.

Conclusions

Freeflow, the newly developed uroflowmeter, enabled us to determine the fluctuations in the measurements recorded at home and the differences between daytime and nighttime. Thus, creating a nomogram for objectively examining nighttime urination status and utilizing a urination diary was found to be effective for providing correct diagnosis and treatment of lower urinary tract symptoms.

自由流:新型便携式尿流仪可以帮助实现实际的泌尿状况在家里

目的评价一种新型便携式尿流量仪Freeflow在检测家庭实际排尿状况中的有效性。方法43例良性前列腺增生患者在医院和家中使用无积尿的Freeflow尿流量仪。我们制作了每位患者的尿量和最大尿流率(Qmax)的nomogram。此外，我们还调查了每位患者的实际排尿状况。我们还调查了白天和夜间排尿状况的差异。结果43例患者中，40例能够在医院提供必要的数据，所有患者都提供了在家测量的数据。居家评估的试用期为2-7天。在平均尿量方面，住院患者与在家患者无显著差异;然而，Qmax和平均流量(Qave)在家里明显更高。平均变异系数非常大。观察30例患者白天和夜间的关系;夜间尿量明显增加;Qmax和Qave无显著性差异。几天的图和完整的尿日记有助于显示白天和夜间的排尿特征。结论Freeflow，新开发的尿液流量计，使我们能够确定在家里记录的测量波动和白天和夜间的差异。因此，创建一个客观检查夜间排尿状态的图，并利用排尿日记，可以有效地提供正确的诊断和治疗下尿路症状。

期刊介绍： LUTS is designed for the timely communication of peer-reviewed studies which provides new clinical and basic science information to physicians and researchers in the field of neurourology, urodynamics and urogynecology. Contributions are reviewed and selected by a group of distinguished referees from around the world, some of whom constitute the journal''s Editorial Board. The journal covers both basic and clinical research on lower urinary tract dysfunctions (LUTD), such as overactive bladder (OAB), detrusor underactivity, benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), urinary incontinence, pelvic organ prolapse (POP), painful bladder syndrome (PBS), as well as on other relevant conditions. Case reports are published only if new findings are provided. LUTS is an official journal of the Japanese Continence Society, the Korean Continence Society, and the Taiwanese Continence Society. Submission of papers from all countries are welcome. LUTS has been accepted into Science Citation Index Expanded (SCIE) with a 2011 Impact Factor.
