基于CT定位针刺曲骨穴至膀胱壁治疗良性前列腺增生的针刺深度影响因素研究

Study on Factors Influencing Depth of Needling RN2 to Bladder Wall for Treatment of BPH Based on CT Localization

目的:基于CT定位测量针刺曲骨穴至膀胱壁的针刺深度,探究体质量指数、两侧髂前上棘间距离、腰围、臀围、前列腺体积和膀胱残余尿量对针刺深度的影响。方法:纳入符合良性前列腺增生诊断标准的患者31例,测量患者的臀围、体质量指数、腰围、两侧髂前上棘间距离、前列腺体积、膀胱残余尿量以及CT定位下针刺曲骨穴至膀胱壁的深度等临床数据。运用多元线性回归分析筛选针刺深度拟合效果最好的多元线性回归方程。结果:针刺曲骨穴至膀胱壁的针刺深度(Depth,cm)=0.885×臀围-0.218×膀胱残余尿量-0.153×前列腺体积-13.719,方程具有统计学意义(F=14.537,P<0.01)。结论:针刺曲骨穴至膀胱壁的针刺深度与臀围、膀胱残余尿量和前列腺体积拟合效果最好,臀围对针刺深度影响最大。

Objective:To measure the depth of needling Qugu(RN2)to bladder wall based on CT localization,thus to investigate the influence of body mass index,distance between bilateral anterior and superior iliac spines,waist circumference,hip circumference,prostate volume,and residual urine volume on the needling depth.Methods:31 patients who met the diagnostic criteria for benign prostatic hyperplasia(BPH)were included.Clinical data such as hip circumference,body mass index,waist circumference,distance between anterior and superior iliac spines on both sides,prostate volume,residual urine volume in the bladder,and depth of needling RN2 to bladder wall were measured under CT localization.Multiple linear regression analysis was used to screen the multiple linear regression equation that best fitted the needling depth.Results:The depth of needling RN2 to bladder wall(Depth,cm)was equal to 0.885×hip circumference-0.218×bladder residual urine volume-0.153×prostate volume-13.719,with statistical significance(F=14.537,P<0.01).Conclusion:The depth of needling RN2 to the bladder wall is best fitted by hip circumference,residual urine volume,and prostate volume.Among these factors,hip circumference has the greatest impact on the needling depth.
