Analysis of normal uroflow curves with two different methods give evidence that the uroflow is fractal. It is possible to synthesize uroflow-like curves with the fractal interpolation technique of Barnsley, which may become a way to characterize clinical measurements. Differences between real and synthetic uroflow curves appear when the Lyapunov exponent (a measure of complexity) is calculated: the synthetic curves appear chaotic in this respect, as opposed to the real flow curves.
用两种不同方法对正常尿流曲线进行分析表明尿流具有分形特征。利用巴恩斯利的分形插值技术可以合成类似尿流的曲线，这可能成为一种表征临床测量结果的方法。在计算李雅普诺夫指数（一种复杂性度量）时，真实尿流曲线和合成尿流曲线之间出现了差异：在这方面，合成曲线显得混沌，而真实尿流曲线并非如此。
