尿动力学检查在前列腺增生症术前评估中的临床意义

The value of urodynamic studies before prostatectomy in BPH

目的探讨前列腺增生症(BPH)手术治疗前尿动力学检查的必要性。方法对166例拟行手术治疗的BPH患者的尿动力学检查结果进行分析。结果在166例患者中,125例(75.3%)证实存在膀胱出口梗阻(BOO+),25例(15.1%)为可疑BOO(BOO±),16例(9.6%)无BOO(BOO-),3组之间在最大尿流率(Qmax)、残余尿量(PVRV)、逼尿肌/外括约肌协同失调(DSD)上差异无统计意义,BOO(+)组的逼尿肌不稳定(DI)、低顺应性膀胱的发生率明显高于其他两组,逼尿肌收缩力减弱(DUA)的发生率明显低于其他两组。结论尿动力学检查对诊断BPH、选择治疗方法和预测疗效有重要意义,手术治疗前应常规检查。

Objective To determine the value of urodynamic studies before prostatectomy on patients with BPH. Methods The urodynamic data of 166 patients with BPH who had been prepared to undergo prostatectomy were studied. Results In 166 patients, 125 patients had bladder outlet obstruction （BOO） ,25 patients had suspicious BOO and 16 patients had no BOO. There was no statistic difference in Qmax, PVPR and DSD among the three groups. The group BOO is higher in the incidence of DI and low compliance,and lower in the incidence of DUA than the other groups. Conclusion Urodynamic studies can provide clear information about the detrusor function and the bladder outlet. It is necessary for those patients with BPH before prostatectomy to do urodynamic studies.
