尿流动力学在前列腺增生诊断中的作用

摘要

目的：评价尿流动力学检查在诊断前列腺增生所致的下尿路症候群中的作用。方法采用尿动力学检查仪常规行尿流率、压力-流率测定及尿道测压，并测尿道外括约肌电图及残余尿量。对膀胱逼尿肌情况进行详细的记录，在掌握膀胱顺应性和尿道外括约肌的协调情况的基础上对BOO作出诊断。结果本组患者427例，340例患者被诊断为BOO，5例被确诊为无BOO，82例属于BOO可疑者。其中137例患者同时存在膀胱低顺应性，70例患者的膀胱逼尿肌功能已经受到损害，113例患者属于不稳定膀胱者。随着BOO程度加重，膀胱顺应性呈下降趋势。结论尿流动力学检查在诊断前列腺增生中极其重要，是下尿路症候群不可缺少的检查仪器。良性前列腺增生（BPH）是老年男性常见病、多发病，也是导致BOO（膀胱出口梗阻）的主要原因。而BOO的准确诊断对临床治疗极其重要。目前为止尿流动力学检查已被公认为是诊断BOO的金标准。%ObjectiveTo evaluate the role of urinary lfow dynamics in the diagnosis of lower urinary tract syndrome caused by benign prostatic hyperplasia.Methods The urine lfow rate, pressure lfow rate and urethral pressure were measured and the residual urine volume was measured. The bladder detrusor of detailed records, in controlling the bladder adaptation and external urethral sphincter coordination on the basis of BOO diagnosis is made.Results In this group, 427 patients, 340 patients were diagnosed as BOO, 5 cases were diagnosed as no BOO, 82 cases of suspicious persons belonging to BOO. The 137 patients exist at the same time low compliance bladder, 70 patients with bladder detrusor function has been damaged, 113 cases of patients belongs to the unstable bladder. With the degree of BOO increased, the bladder compliance decreased.Conclusion The examination of the urine lfow dynamics is very important in the diagnosis of prostatic hyperplasia. It is an indispensable inspection instrument for lower urinary tract syndrome. Benign prostatic hyperplasia (BPH) is a common and frequently occurring disease in elderly men, and it is also the main cause of BOO (bladder outlet obstruction). And the accurate diagnosis of BOO is very important for clinical treatment. So far, the examination of the urine lfow dynamics has been recognized as the gold standard for diagnosis of BOO.
