Motivation: USD patients are currently evaluated with RUG which provides limited information. USD patients cannot undergo UDS studies to evaluate their bladder or urethral function given their obstruction.
Goal(s): To develop a non-invasive MRI based CFD tool to comprehensively evaluate the LUT in USD patients.
Approach: One healthy volunteer and two USD patients were imaged with our MRI urodynamic protocol and a voiding event was simulated with CFD.
Results: USD patients demonstrated higher urine velocities, increased wall shear stress, and pressure gradients across the strictured segment compared to non strictured urethras relative to flow.
Impact: USD patients are currently restricted in which methods can be employed to evaluate their bladder/urethral function. This study develops a non-invasive MRI based CFD tool to rigorously evaluate the LUT in USD patients.
