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(V_P)等临床数据及尿动力学检查结果进行相关性分析。随访1 2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、V_P组间相比差异无统计学意义(P>0.05),Qmax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1 2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。
Objective To investigate the relationship between the length of bladder invagination (BPO) and bladder outlet obstruction (BOO) measured by transabdominal sonography in patients with benign prostatic hyperplasia (BPH). Methods 87 cases of BPH patients, according to the sagittal sagittal ultrasound to measure the distance from the bladder base to the prostate into the bladder into the top of the bladder in varying degrees of grade Ⅰ, Ⅱ and Ⅲ grade 3 groups, while urodynamic examination, Age, International Prostate Symptom Score (I-PSS), maximal uroflow rate (Q max), residual urine volume (PVR) and prostate volume (V_P) were analyzed. Followed up for 12 months, repeat the above examination and correlation analysis. Results There was no significant difference in age, I-PSS, PVR and V_P between the three groups (P> 0.05), but there was a significant difference between Qmax and obstruction group (P <0.01) The level of IPP was positively correlated with the degree of BOO (P <0.01). With the prevention of 1-2 months, 22 patients due to clinical progress require medication or surgical treatment, including grade Ⅰ to grade Ⅱ in 5 cases, Ⅱ grade to grade Ⅲ in 5 cases. Statistical analysis of the three groups of clinical data with the former, the level of IPP and the degree of BOO was positively correlated (P <0.01). Conclusions The measured Q max of IPP measurement combined with uroflowmeter can be used to evaluate BPH and the degree of obstruction.
