| 摘 要： | 目前众多的经尿道微创术式治疗良性前列腺增生(BPH)均通过扩大或再造前列腺段尿道(PU)的腔内空间发挥作用,因此,探讨BPH微创术后PU形态对排尿的力学影响,具有重要的指导意义。本研究采用计算流体力学(CFD)技术探讨PU/膀胱颈横径比(RPU-1)对尿流的影响。结果表明,在RPU-1>0.79时,PU两侧出现涡流;且涡流随RPU-1增大而增大,相应的尿道出口流速则逐渐降低。CFD技术可量化模拟PU内的涡流行为,揭示RPU-1所反映的PU腔内空间对尿流动力学的客观影响,是无创尿流动力学研究的可用方法。

| 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. |
