IPSS与前列腺体积、前列腺膀胱内突出度、最大尿流率、残余尿及体重指数相关性的研究价值

Study on the relations between IPSS and prostate volume,intravesical prostatic protrusion,Qmax,residual urine,BMI

目的 探讨良性前列腺增生（benign prostatic hyperplasia,BPH）患者前列腺体积、前列腺膀胱内突出度（intravesical prostatic protrusion,IPP）、最大尿流率（Qmax）、残余尿及体重指数（body mass index,BMI）与前列腺症状评分（international prostate symptom score,IPSS）的相关性.方法 采用泌尿系彩超、尿流率检查得出相关数据,分析其与IPSS的相关性,得出估算IPSS的方法.结果 IPSS与前列腺体积有明显的相关性（P=0.025）;与膀胱内前列腺突出度有明显的相关性（P=0.000）;与尿流率有明显的相关性（P=0.000）;与体重指数相关性不显著（P=0.603）,最后通过以IPSS为因变量,Qmax、残余尿、IPP为自变量行回归分析得出回归方程式：IPSS=24.202＋ 1.587×IPP （cm） ＋0.033×残余尿（mL）-0.469×Qmax （ml/s） （F=13.273,P=0.000）.结论 前列腺体积、IPP、Qmax、残余尿与IPSS明显相关;可通过IPP、Qmax残余尿的测量,用公式“IPSS=24.20＋1.59×IPP（cm） ＋0.03×残余尿（mL）-0.47×Qmx （ml/s）”估算IPSS有一定意义.

Objective To discuss the relevance of international prostate symptom score with prostatic volume,intravesical prostatic protrusion, Q residual urine volume, body mass index of the benign prostatic hyperplasia patients. Methods The relative data collected from urinary system ultrasound and urine flow rate detection were analyzed and the correlation with IPSS was determined. The calculation method of IPSS score was deduced. Results There were significant correlations for IPSS score with prostate volume （P=-0.025）; with intravesical prostatic protrusion .（P=0.000）; with Qmax, （P=0.000）, whereas there was no significant correlation for IPSS score with body mass index significantly （correlation=-0.054, P=0.603）. If the IPSS score was set as the dependent variable, Q residual urine volume and IPP as the independents, the regression equation will be obtained. IPSS=24.202＋1.587 × IPP（cm）＋0.033 × RUV（ml）-0.469 × Qmax（ml/s） （F=13.273, P=0.000）. Conclusion The prostate, IPP, Qmax, and residual urine volume were significantly related with IPSS. The formula of the IPSS score can be estimated with the data of IPP, Qmax and residual urine volume.
