Abstract

A computational model was presented to simulate peristaltic transportation of urine isolated bolus through the ureter. In this model, muscular stimulation was implemented using fluid-structure interaction and contact analysis. Urine drainage to the bladder was analyzed using two methods of numerical simulation and sonographic imaging in the region of bladder near the ureteral orifice. Moreover, pressure distribution in the ureter and dynamic variations of urine back flow during PERISTALSIS were investigated. The results indicated that when URINE BOLUS reached near the bladder, the maximum magnitude of urine pressure in the ureter increased up to nearly 5 times the ureteral inlet pressure. The average magnitude of urine flow rate computed from velocity profile in ureteral outlet during urine drainage was 2.267 ml/min.
