Inverse Method for Ureteral Peristalsis Determination from Pressure Measurements

We present a method to determine ureteral peristalsis wave shapes, incorporating the longitudinal wall motion of Kalayeh et al. (2023). With synthetic pressure data, our inverse algorithm accurately identifies wave shapes, longitudinal motion, and potential reflux. In vivo pressure measurements to compare to the model would require a ureteral catheter with two pressure ports separated by an appropriate distance to find the wave speed and the pressure offset over one wavelength.
