Real-Time Magnetic Resonance Imaging-Based Computational Modelling To Simulate Urine Flow In Urethra

Abstract

Studying common urinary conditions such as BPH/LUTS require measuring urine flow in the urethra by invasive techniques. We present a method that uses real-time MR images of the bladder and urethra to quantify urine flow dynamics. Images of the urethra define the anatomical geometry, while images of the bladder inform the flow rate inside the urethra. Coupling MRI with CFD allows the urinary flow simulation inside the urethra providing information about urine velocity, pressure, and wall shear stress non-invasively.
