摘要

目的

探讨仿真厕所在尿动力检测中对尿流率的影响。

方法

选取2021年10月至2022年9月在新乡医学院第一附属医院就诊并经过筛查排除后最终入组的120例男性患者为研究对象，根据排尿状况分为两组进行评估，每组60名，分别为正常排尿组和异常排尿组。收集患者基本信息(年龄、身高、体质量、饮酒情况、既往病史、手术史等)，研究对象分别通过仿真厕所尿流率测定和传统尿流率测定进行两次排尿，比较两种尿流的最大尿流率(Qmax)、平均尿流率(Qave)、尿流量、排尿时间、达峰时间和患者满意度调查评分。

结果

在比较所有120名男性患者时，传统尿流率检测和仿真厕所尿流率检测的尿流参数以及对两次尿流率检测的患者满意度调查评分之间的差异具有统计学意义（

0.05），传统尿流率测定的Qmax、Qave、尿流量、排尿时间、达峰时间均低于仿真厕所尿流率检测，传统测量方法的满意度评分低于仿真厕所。Qmax受不同排尿状况下不同检测方法检测的影响不同。分别在正常排尿组与异常排尿组中，两种尿流率检测方法的尿流参数之间差异均具有统计学意义（

0.05），传统方式测量的Qmax、Qave、尿量均低于仿真厕所组，仿真厕所排尿的达峰时间更久，其排尿时间也更长。

结论

仿真厕所尿流率检测更贴近日常排尿状况，可以提供给患者更舒适的感受，相较于传统尿流率测定，仿真厕所尿流率检测能得到更加符合真实排尿情况的尿流率测定结果。

Abstract

Objective

To explore the effect of the simulated toilet on the urinary flow rate in urodynamic tests.

Methods

A total of 120 male patients admitted to the First Affiliated Hospital of Xinxiang Medical University from October 2021 to September 2022 were selected and divided into two groups according to their urination status. The 120 patients were divided into a normal urination group and an abnormal urination group

with 60 patients in each group. Basic information of the patients (age

height

weight

alcohol consumption

past medical history

surgical history

etc.) was collected. The subjects urinated twice in simulated uroflowmetry and conventional uroflowmetry

respectively. The maximum flow rate (Qmax)

average flow rate (Qave)

voided volume

voiding time

peak time

and patient satisfaction scores were compared between the two methods of uroflowmetry.

Results

There was statistical significance in the urine flow parameters and patient satisfaction survey scores between the traditional urine flow rate test and the simulated toilet urine flow rate test (

0.05). The Qmax

Qave

urine flow rate

urination time

and peak time measured by the traditional urine flow rate test were all lower than those measured by the simulated toilet

and the satisfaction score of the traditional measurement method was lower than that of the simulated toilet. Qmax was affected differently by different detection methods under different urination conditions. The urine flow parameters of the two methods were statistically significant between the normal and abnormal urination groups (

0.05). The Qmax

Qave

and urine volume measured by the traditional method were all lower than those in the simulated toilet group

and the simulated toilet group had a longer peak time and longer urination time.

Conclusion

The simulated toilet uroflowmetry is closer to the daily urination situation and can provide patients with a more comfortable experience. Compared with the traditional uroflowmetry

the simulated uroflowmetry can obtain urine flow rate test results that are more consistent with the actual urination situation.
