Uroflowmetry is a non invasive objective criterion for the evaluation of micturition. The values depend on resistance to voiding, but also detrusor pressure. Correct interpretation must take into account the limits of the examination, related to voiding volume, number of micturitions, age, individual factors, and circadian variations. Some artefacts, such as the initial peak or abdominal straining, induce a difference between automatic reading and manual reading, justifying comparison of the result displayed with the appearance of the curve. Uroflowmetry can detect dysuria, which may be poorly perceived or even unknown to the subjects themselves. It also completes the data of symptom scores. It is a good criterion for assessment of the results of treatment, but is insufficient, on its own, to define surgical indications. There is no strict correlation between flow rate and residual volume.
尿流率测定是评估排尿功能的一种非侵入性客观标准。其数值取决于排尿阻力，也与逼尿肌压力有关。正确解读必须考虑到检查的局限性，这些局限性与排尿量、排尿次数、年龄、个体因素以及昼夜变化有关。一些伪像，如初始峰值或腹部用力，会导致自动读数和手动读数之间存在差异，这就需要将显示的结果与曲线外观进行比较。尿流率测定可以检测出排尿困难，而患者自身可能对此感知不佳甚至毫无察觉。它还能完善症状评分数据。它是评估治疗效果的良好标准，但仅凭其自身不足以确定手术指征。流速与残余尿量之间没有严格的相关性。
