摘　　要：目的探讨一种无创性的尿动力学方法(尿流率-尿道括约肌EMG同步检测)在慢性前列腺炎(CP)临床诊治中的作用。方法对128例CP患者和30例正常人进行尿流率-尿道括约肌EMG同步检测,用Qmax、Qave、TL值和EMGlagTime参数分析尿流率-尿道括约肌EMG。结果Qmax、Qave和TL值在CP组与正常对照组比较时均明显降低,差异有统计学意义(P<0.05);128例CP患者排尿时尿道括约肌肌电活动异常共107例(占83.6%),EMGlagTime异常7例(占5.5%);CP患者TL值与Qmax之间存在正相关关系(r=0.864,P<0.001),与NIH-CPSI之间存在负相关关系(r=-0.762,P<0.001)。结论尿流率-尿道括约肌EMG检测是评估功能性下尿路梗阻的无创且简便有效的方法,在CP的诊治及疗效评估中具有重要临床指导意义,值得推广应用。[ Objective ] To investigate the effects of the uroflow rate-EMG in chronic prostatitis. [Methods ] 128 patients with chronic prostatitis and 30 normal persons were both examined by laborie urodynamic system. The Qmax, Qave, TL value and EMG lag Time were used to explain the Uroflow Rate-urethral sphincter EMG. [ Restilts ] The Qmax, Qave and TL value in CP group were significantly lower than those in normal contrast group （P〈 0.05）; 107 cases had abnormal urethral sphincter EMG in the 128 cases patients （83.6%）, and 7 cases had abnormal EMG lag Time （5.5%）. There was a positive correlation between TL value and Qmax （r =0.864,P 〈0.001）, and there was a negative corelation between TL value and NIH-CPSI （r =-0.762,P 〈0.001）. [ Conclusions] The uroflow rate-EMG technique is a noninvasive, simple, effective method for evaluating lower urinary tract obstruction, and it would play an important role in diagnosis of chronic prostatitis and is useful for clinical practice.
