良性前列腺增生向膀胱内突入部分的长度与膀胱出口梗阻程度的相关性研究

目的 探讨经腹超声测定良性前列腺增生(BPH)向膀胱内突入部分(IPP)的长度与膀胱出口梗阻(BOO)程度的相关性.方法 BPH患者87例,根据经腹矢状面超声测量膀胱基底到前列腺向膀胱内突入顶端的距离不同程度分Ⅰ级、Ⅱ级和Ⅲ级3组,同时行尿动力学检查,将各组间年龄、国际前列腺症状评分(Ⅰ-PSS)、最大尿流率(Q max)、剩余尿量(PVR)、前列腺体积(Vp)等临床数据及尿动力学检查结果进行相关性分析.随访12个月,重复上述检查及相关性分析.结果 3组临床资料中,年龄、Ⅰ-PSS、PVR、Vp组间相比差异无统计学意义(P＞0.05),Q_(max)和梗阻率组间相比差异有统计学意义(P＜0.01),IPP的水平与BOO的程度呈正相关(P＜0.01).随防12个月后,22例患者因临床进展需要药物或手术治疗,其中Ⅰ级进展至Ⅱ级为5例,Ⅱ级进展至Ⅲ级为5例.3组临床资料的统计学分析同前, IPP的水平与BOO的程度呈正相关(P＜0.01).结论 IPP测量联合尿流率仪所测得Q_(max)可以初步评价BPH及其所致梗阻程度.

Study on the relationship between the degree of intravesical prostatic protrusion and the severity of bladder outlet obstruction

Objective To study the relationship between the degree of intravesical prostatic protrusion (IPP) and the severity of bladder outlet obstruction (BOO) and its clinical significance for benign prostatic hypertrophy(BPH)patients.Methods Total of 87 patients with BPH were divided into 3 groups according to the degree of IPP, such as group 1 (Grade Ⅰ, IPP＜5mm), group 2 (Grade Ⅱ, 5-10mm), group 3 (Grade Ⅲ, ＞10mm).All patients received Urodynamic examinations.The relationship of clinic data and urodynamic outcome was analyzed among three groups.After 12 months follow up, the clinic date and pressure-flow study were assessed again.Results There were no statistical significances in age, prostatic volume, postvoid residual urine volume and IPSS in three groups (P＞0.05),there was statistical significance in the Q_(max) and A-G number (P＜0.01).After 12 months, 22 patients were excluded because of urine tract infection and urine retention, Same results were found in the three groups.Grade Ⅲ IPP was positively correlated with BOO index (P＜0.01).Conclusion The measurements the IPP and Q_(max) was used to predict the extent of BOO and function of detrusor of BPH.
