摘要
目的：分析良性前列腺增生（BPH）患者中叶增生大小与膀胱出口梗阻（BOO）程度之间的相关性。方法：对2008年5月~2010年6月因排尿困难就诊的BPH患者131例,通过经腹超声测定前列腺三径和前列腺突入膀胱的距离（IPP）,尿动力学检查测定最大尿流率（Qm ax）、最大尿流率时的逼尿肌压力（Pdet@Qm ax）,利用L in-PURR图判断梗阻级别和逼尿肌收缩力,并计算出AG值（AG=Pdet@Qm ax-2Qm ax）。不同IPP梗阻程度的比较采用方差分析,并对前列腺体积（PV）、IPP与AG值进行相关性分析。结果：当IPP〉10 mm时,IPP与BOO高度正相关（相关系数r=0.821,P〈0.01）。PV与BOO相关度较低（r=0.475,P〈0.01）。IPP与Pdet@Qm ax高度正相关（r=0.865,P〈0.01）。结论：前列腺中叶增生与BOO存在高度相关性,超声测定中叶突入膀胱的距离是判断BOO程度较为可靠的方法。
Objective： To analyze the correlation between the size of prostatic middle lobe hyperplasia and the degree of bladder outlet obstruction（BOO） in patients with benign prostatic hyperplasia（BPH）.Methods： This study included 131 BPH patients who presented with dysuria between May 2008 and June 2010.The prostate volume and intravesical prostatic protrusion（IPP） were measured by transabdominal ultrasound,Qmax and detrusor pressure at Qmax（Pdet@Qmax） detected by urodynamic examination,the obstruction degree and detrusor contractility judged using the LinPURR Figure,and the AG value calculated（AG=Pdet@Qmax-2Qmax）.The degrees of BOO were compared between different groups of IPP by variance analysis,and the prostate volume,IPP and AG values underwent Bivariate correlation analysis.Results： IPP was highly positively correlated with BOO when it was 10 mm（r = 0.821,P0.01）,while PV and BOO had a lower correlation（r = 0.475,P0.01）.There was also a high positive correlation between IPP and Pdet@Qmax（r = 0.865,P0.01）.Conclusion： A close correlation exists between prostatic middle lobe hyperplasia and BOO,and evaluating IPP by ultrasound is a reliable method to determine the degree of BOO.
