静态尿道压力测量在诊断BPH所致膀胱出口梗阻中的作用

目的　探讨静态尿道测压 (UPP)在诊断BPH致膀胱出口梗阻 (BOO)中的作用。方法　 5 1例BPH患者行尿动力学检查 ,经压力 -流率测定其中 42例诊断为BOO ,设为梗阻组 ,另 9例为非梗阻对照 ,比较两组UPP及B超检查的各项指标 ,并行有关的相关分析。结果　 ( 1)UPP测定的前列腺长度与B超测定的前列腺体积呈显著正相关 ( r =0 .91,P <0 .0 5 )。 ( 2 )除最大尿道闭合压外 ,梗阻组的平均膀胱颈压、前列腺长度、控尿区面积及前列腺体积显著大于对照组 (P<0 .0 5 )。 ( 3 )前列腺体积与IPSS评分、梗阻程度之间不存在相关关系。结论　UPP检查主要反映BPH所致后尿道结构和前列腺体积的改变 ,对BPH的治疗有一定指导意义 ,但在诊断膀胱出口梗阻方面的价值不大。

Significance of urethral pressure profile on diagnosing bladder outlet obstruction in BPH

Objective To investigate the value of static urethral pressure profile (UPP) in the diagnosis of BPH.Methods 51 BPH patients underwent urodynamic test,according to pressure-flow study,42 cases were stratified into obstructive group,9 cases into unobstructive group.UPP and ultrasound examiation were performed in both groups.Results 1.The prostate length measured by UPP had a significantly positive relationship with prostate volume (r=0.91,P<0.05),2.Except the maximum urethral closure pressure,there were significant differences in UPP indexes and prostate volume between two groups (P<0.05).3.No relative correlations were observed between prostate volume and obstruction degree,or between prostate volume and International Prostate Syndrome Score (IPSS).Conclusion UPP could reflect anatomical changes in posterior urethra and prostate volume indirectly,which is useful for the treatment of BPH,but UPP seems has minimal value on the diagnosis of BOO.
