腹部B型超声检查在良性前列腺增生症患者膀胱出口梗阻诊断中的应用

Application of transabdominal ultrasonography in diagnosis of bladder outlet obstruction in patients with benign prostatic hyperplasia

目的:通过分析良性前列腺增生症(BPH)患者超声测量膀胱质量(BW)、膀胱内前列腺突入程度(IPP)与膀胱出口梗阻(BOO)程度之间的相关性,探讨超声检查在预测BPH患者BOO的应用价值。方法:124例BPH患者行尿动力学检查,以尿动力学检查结果分成2组(梗阻组与非梗阻组)。经腹部B超测量BW及IPP,并将2组所测结果与尿动力学检查结果比较。结果:梗阻组和非梗阻组患者的BW分别为(77.47±44.34)g和(57.47±23.10)g,组间比较差异有统计学意义(P<0.05);IPP分别为(11.05±9.65)mm和(7.67±7.99)mm,组间比较差异有统计学意义(P<0.05)。全组患者BW与最大尿流率(Qmax)呈显著负相关(r=-0.177,P<0.05),与最大逼尿肌压(PdetQmax)呈显著正相关(r=0.201,P<0.05);IPP与Qmax呈显著负相关(r=-0.403,P<0.01),IPP与PdetQmax呈显著正相关(r=0.192,P<0.01)。结论:BW及IPP与BOO存在显著相关性,是判断BOO程度较为可靠的方法。腹部B型超声检查可用于评估BPH梗阻程度,指导治疗。

Objective To analyze the correlation between the bladder weight（BW） and intravesical prostatic protrusion（IPP） and the degree of bladder outlet obstruction（BOO） in the patients with benign prostatic hyperplasia（BPH） and to explore the clinical value of transabdominal ultrasonography in judgement of BOO in the patients with BPH.Methods Urodynamic examination was performed in 124 BPH patients from March 2009 to January 2011.124 patients were divided into 2 groups（non-obstruction and obstruction）.The BW and IPP were measured by transabdominal ultrasonography,the correlation between BW,IPP and the parameters reflecting BOO was analyzed.Results The BW values in obstruction group and non-obstruction group were（77.47±44.34） g and（57.47±23.10） g.There was significant difference in BW between obstruction group and non-obstruction group（P〈0.05）.The IPP values in obstruction group and non-obstruction group were（11.05±9.65） mm and（7.67±7.99） mm.There was significant difference in IPP between obstruction group and non-obstruction group（P〈0.05）.The BW value of all the patients with BPH was negatively correlated with Qmax（r=-0.177,P〈0.05） and positively correlated with PdetQmax（P〈0.05,r=0.201）.The IPP value was negatively correlated with Qmax（r=-0.403,P〈0.01） and positively correlated with PdetQmax（r=0.192,P〈0.01）.Conclusion The BW and IPP are highly correlated with BOO,and evaluating BW and IPP with ultrasound is a reliable method to determine the degree of BOO.
