To develop the visual uroflow scale (VUS), analyze the relationship of VUS score and index of free uroflowmetry, assess urination function preliminarily and improve the work efficiency in the clinic.
Male lower urinary tract symptoms (LUTS) patients, who attended the Department of Urology in Peking University People's Hospital from March 2016 to March 2017, were assessed for their urination function according to the Visual Uroflow Scale without help from clinicians before undertaking a free uroflowmetry test. And afterwards, a free uroflowmetry was undertaken, and variables including maximal flow rate (Qmax), the average flow rate (Qave) and voiding volume (VV) was obtained. During the study, 124 cases were collected and 53 cases met the inclusion and exclusion criteria and were included in the study cohort. The Spearman correlation analysis was used for analyzing the correlation of VUS scores with free uroflowmetry variables and age. The validity of VUS was evaluated.
Most of the patients could choose the very figure matched with self-condition by first instinct without any help from the clinician. The data were analyzed by Spearman correlation analysis. In the present study, voiding time was positively correlated with the VUS score (correlation coefficient, 0.62, < 0.05). In the present cohort, the patients chose the third and fourth figures to take longer time to urinate, implying worse LUTS situation. Flow time and VUS scores were positively correlated (correlation coefficient, 0.61, < 0.05). The patients with higher VUS scores would spend more time on urinate, no matter how long urinary hesitation was. Both Qmax and Qave were negatively correlated with the VUS score (correlation coefficient －0.54, －0.62, < 0.05). The study illustrated that the VUS score suggested that the Qmax basically and further reflected the urination function. And its relationship to age revealed the decreased urination function of aging male, which had reached a consensus.
Development of VUS has helped the clinician assess the urination function preliminarily at the first time. Patients are assessed for a VUS score before getting surgery or receiving the drug for treatment, and can be re-assessed after. The VUS score can provide an objective quantitative basis to evaluate the treatment efficacy. In addition, considering that it is convenient, timesaving and easy to understand, the VUS is available for follow-up.
研发视觉尿流量表（VUS），分析VUS评分与自由尿流率指标的关系，初步评估排尿功能，提高临床工作效率。
选取2016年3月至2017年3月在北京大学人民医院泌尿外科就诊的男性下尿路症状（LUTS）患者，在进行自由尿流率检测前，由患者根据视觉尿流量表自行评估排尿功能，无需临床医生协助。之后进行自由尿流率检测，获取包括最大尿流率（Qmax）、平均尿流率（Qave）和排尿量（VV）等变量。研究期间，共收集124例病例，其中53例符合纳入和排除标准，纳入研究队列。采用Spearman相关分析，分析VUS评分与自由尿流率变量及年龄的相关性，评估VUS的有效性。
多数患者能凭第一直觉选择与自身情况相符的图形，无需临床医生提示。采用Spearman相关分析对数据进行分析。本研究中，排尿时间与VUS评分呈正相关（相关系数为0.62，P<0.05）。在本队列中，患者选择第三和第四幅图形排尿时间较长，提示LUTS情况较差。尿流时间与VUS评分呈正相关（相关系数为0.61，P<0.05）。无论排尿犹豫时间长短，VUS评分较高的患者排尿时间更长。Qmax和Qave均与VUS评分呈负相关（相关系数分别为－0.54、－0.62，P<0.05）。研究表明，VUS评分基本能反映Qmax，进一步反映排尿功能。其与年龄的关系揭示了老年男性排尿功能下降，这已达成共识。
VUS的研发有助于临床医生首次初步评估排尿功能。患者在手术或接受药物治疗前评估VUS评分，治疗后可再次评估。VUS评分可为评估治疗效果提供客观定量依据。此外，鉴于其方便、省时且易于理解，VUS可用于随访。
