ABSTRACT
It is important to investigate the mechanical effects of morphology of prostatic urethra (PU) for benign prostatic hyperplasia (BPH). PU and bladder neck transverse diameter ratio (RPU-1), which related to vortex, and their influence on urine flow were observed by CFD. The results showed that vortexes appeared and expanded with increasing RPU on both sides of PU when RPU-1>0.79, and velocity of external urethral orifice decreased gradually. CFD is an available method for urodynamics research. The quantitative simulation of the relationship between RPU-1 and vortex was proposed for the first time, providing a new idea for advancing theory of PU lumen repair in BPH.
