摘要
目的探讨良性前列腺增生（BPH）患者B超检查发现膀胱小梁形成在判断膀胱出口梗阻程度及膀胱功能状态中的作用。方法前瞻性比较BPH经腹B超检查显示有膀胱小梁形成与无膀胱小梁形成2组患者临床资料及尿动力学检查参数。结果有膀胱小梁形成BPH患者36例，无膀胱小梁形成患者68例，年龄分别为（73．7±10．1）岁和（69．6±6．2）岁，国际前列腺症状评分分别为（24．4±6．6）分和（22．8±8．3）分，2组比较差异无统计学意义（P〉0．05）；2组最大尿流率时逼尿肌压力分别为（131．7±57．3）cmH2O（1emH2O=0．098kPa）和（92．1±47．8）cmH2O，线性被动尿道阻力关系梗阻程度分级分别为4．6±1．1和3．5±1．5，2组比较差异有统计学意义（P〈0．05）；72．2％（26／36）的小梁形成患者膀胱顺应性减低，其中23．1％（6／26）出现双。肾积水，造成肾功能损害；无小梁形成组分别为42．6％（29／68）和10．3％（3／29），2组比较差异具有统计学意义（P〈0．05）。结论BPH患者B超检查发现膀胱小梁形成，提示存在膀胱出口梗阻，上尿路积水风险增大；无尿潴留者，膀胱小梁形成提示膀胱功能尚处于代偿期，应及时解除梗阻，有利于膀胱功能恢复，减少并发症的发生。
Objective To study the role of B-mode ultrasound found bladder trabeculation in evaluating the degree of bladder outlet obstruction （BOO） and the bladder function in benign prostatic hyperplasia （BPH） patients. Methods Conducted prospective research to determine differences in clinical data and urodynamic parameters between BPH patients with and without bladder trabeculation diagnosed by abdominal ultrasound. Results Thirty-six BPH patients with bladder trabeculation were compared with 68 BPH patients without bladder trabeculation. The mean age was （73.7 ± 10.1 ） years for the patients with bladder trabeculation and （69.6 ±6.2） years without bladder trabeculation, IPSS was 24.4 ± 6.6 and 22.8 ~ 8.3 respectively, in which no significant differences were found （P 〉 0.05）. The detrusor pressure at maximum flow rate was （ 131.7 ± 57.3 ） em H20 and （92.1 ± 47.8） em H20 ） respectively. The linearized passive urethral resistance relation was 4.6 ± 1.1 and 3.5 ± 1.5 respectively, showing a significant difference （P 〈 0.05） between the two groups. Seventy-two point two percent （26/36） of the patients with bladder trabeeulation had a low compliance bladder, among whom 23.1% （6/26） of the patients had bilateral hydronephrosis with renal insufficiency. The percentage for the control group was 42.6% （29/68） and 10.3% （3/29） respectively （P 〈 0.05 ）, Conclusions The bladder trabeculation found by B-ultrasound in BPH patients suggests the existence of BOO and a high risk of bilateral hydronephrosis. Bladder trabeculation in patients without urinary retention suggests they are in compensation status. Relief of the obstruction is helpful to reeovery of bladder function and the reduction of complications.
