Deep drop: a common finding in uroflowmetry of healthy children and adolescents

This database presents the results of our large-scale cross-sectional study of uroflowmetry tests in healthy children and adolescents. A total of 2299 uroflowmetry curves from 1538 children and adolescents aged 5-18 years were analyzed. Based on the results, we proposed comprehensive criteria for defining “deep drop (DD)” and assess the incidence of DD in the uroflowmetry curves of health subjects. Subsequently, we assessed the accordance with the interpretation of DD with an additional 100 randomly selected uroflowmetry curves from the urology clinic. We hope that this set of criteria will help define staccato uroflowmetry pattern and standardize terminology for future research.

本数据库展示了我们对健康儿童和青少年进行的大规模横断面研究中尿液流速测试的结果。共分析了来自1538名5至18岁儿童和青少年的2299条尿液流速曲线。基于研究结果，我们提出了定义“深度下降（DD）”的全面标准，并对健康受试者的尿液流速曲线中DD的发生率进行了评估。随后，我们通过额外选取来自泌尿科诊所的100条随机尿液流速曲线，对DD的解释与标准的一致性进行了验证。我们期望这套标准能够有助于定义断续尿液流速模式，并标准化未来研究中的术语。
