FRACTALS IN UROFLOWS

Analysis of normal uroflow curves with two different methods give evid ence that the uroflow is fractal. It is possible to synthesize uroflow like curves with the fractal interpolation technique of Barnsley, whic h may become a way to characterize clinical measurements. Differences between real and synthetic uroflow curves appear when the Lyapunov exp onent (a measure of complexity) is calculated: the synthetic curves ap pear chaotic in this respect, as opposed to the real flow curves.
