膀胱内前列腺突出程度与良性前列腺增生临床评价指标的相关性

Correlation of intravesical prostatic protrusion with clinical evaluation parameters in BPH patients

目的:探讨在良性前列腺增生(BPH)患者中,应用经腹超声测量的前列腺向膀胱内突出(IPP)程度与BPH常用临床评价指标的相关性。方法:对275例因下尿路症状就诊的BPH患者行经腹超声通过中线矢状面测量IPP,并且将IPP程度分别与患者年龄、前列腺体积、国际前列腺症状评分(IPSS)、最大尿流率和排尿后残余尿量进行相关分析。结果:275例BPH患者的IPP程度与年龄(r=0.210,P<0.01)、前列腺体积(r=0.534,P<0.01)和排尿后残余尿量(r=0.314,P<0.01)呈正相关关系,与最大尿流率(r=-0.364,P<0.01)呈负相关关系,而与IPSS(r=0.064,P=0.299)无明显相关。结论:IPP程度可能与症状性BPH患者的年龄和前列腺体积存在一定相关性。经腹超声测量IPP可能是一种评价BPH患者膀胱出口梗阻状态及程度的有价值的无创性方法。

Objective：To investigate the correlation of the degree of intravesical prostatic protrusion（IPP）measured by transabdominal ultrasound with the clinical evaluation parameters in BPH patients.Methods：We measured the length of IPP in the mid-sagittal section by transabdominal ultrasound in 275 BPH outpatients with lower urinary tract symptoms,and analyzed the correlations of the degree of IPP with the age,prostatic volume（PV）,international prostatic symptom score（IPSS）,maximum uroflow rate（Qmax）,and postvoid residual urine volume（PVR）of the patients.Results：The degree of IPP was correlated positively with the age（r=0.210,P0.01）,PV（r=0.534,P0.01）and PVR（r=0.314,P0.01）,but negatively with the Qmax（r=-0.364,P0.01）of the BPH patients.There was no significant correlation between the degree of IPP and IPSS（r=0.064,P=0.299）.Conclusion：The degree of IPP may be associated with the age and prostatic volume of BPH patients.Transabdominal ultrasound measurement of IPP is a useful noninvasive method to assess the presence and severity of bladder outlet obstruction in BPH patients.
