尿动力学检测在前列腺增生患者中的意义

目的：分析前列腺增生症患者的尿动力学参数,为个性化治疗前列腺增生症提供依据。方法：2011年1月至2013年1月我科收治800名前列腺增生症患者,经直肠指诊、泌尿系彩超,膀胱镜等初步诊断为前列腺增生,对所有患者进一步行尿动力学检查。结果：本组800例患者中,无梗阻8例;可疑梗阻89例,其中逼尿肌收缩无力23例,逼尿肌收缩乏力66例;膀胱出口明显梗阻（BOO）703例,患者中伴不稳定膀胱132例,低顺应性膀胱486例,不稳定膀胱合并低顺应性膀胱18例。平均最大尿流率（8.2±1.5〕mL/s,平均残余尿量（82.6±75.6）mL,急迫尿意时膀胱容量（280.6±171.3）mL,与同期体检中心健康者正常值比较有差异（P〈0.05）。顺应性（24.4±16.5）mL/cmH2O,与同期体检中心健康者正常值比较无差异（P〉0.05）。结论：尿流动力学检测对前列腺增生症患者具有重要意义。

Urodynamic test in the detection of benign prostatic hyperplasia

Objectives：To analyze urodynamic parameters of patients with benign prostatic hyperplasia（BPH） so as to provide the basis for individualized treatment of the disease.Method：800 BPH patients who came to our hospital between January 2011 and January 2013 were selected.They were preliminarily diagnosed by rectal examination,urinary tract ultrasonography,and cystoscopy as BPH.Urodynamic test was conducted for further diagnosis.Results：Among the 800 patients,there were 8 cases without obstruction,89 with suspicious obstruction of which 23 with detrusor contraction asthenia and 66 with detrusor contraction fatigue.There were 703 cases with bladder outlet obstruction（BOO）,and among 703 cases,132 were complicated with unstable bladder,486 low compliance bladder,18 unstable bladder combined low compliance bladder.The mean maximum urinary flow rate was（8.2 ± 1.5） mL / s,the average residual urine volume was（82.6 ± 75.6） mL,the urge urinary bladder capacity was（280.6 ± 171.3） mL,and these three parameters were of significant differences（P〈0.05） when compared with those of the people who came to our hospital for physical examination during the same time of period.The compliance was（24.4 ± 16.5） mL / cmH2O,and there were no significant differences compared with the people who received physical examination（P〉0.05）.Conclusion：Urodynamic test is effective in the detection of BPH.
