前列腺增生症患者尿动力学检测的临床意义

目的：探讨尿动力学测定在前列腺增生症患者预测手术疗效的价值及能否用于选择手术的临床意义。方法：对有完整尿动力学压力-流率测定资料的67例BPH患者手术前后的国际前列腺症状评分（IPSS）和最大尿流率进行调查。结果：67例患者中膀胱出口梗阻（BOO）65例,2例患者为可疑BOO。存在BOO的65例患者行标准经尿道等离子体前列腺电切术,术后国际前列腺症状评分（IPSS）（16.4±2.6）分较术前（26.3±6.8）分明显降低（P〈0.05）,最大尿流率（Qmax）（11.3±3.5）ml/s较术前（5.9±1.8）ml/s明显提高（P〈0.05）。对于逼尿肌功能不同类型患者术前、术后行国际IPSS和Qmax比较,术后恢复方面无显著性差异（P〉0.05）。结论：尿动力学检查具有直观、准确、量化及可比性高等优点,对BPH患者BOO确诊、判断逼尿肌功能、选择术式及预测疗效等均有重要的参考价值。

Dianostic Value Of urinary dynamic for BPH

Objective：To explore the predicted value of determination on urodynamics in the patitents with benign pro static hyperplasia and in the clinical significance of surgery. Methods：67 cases of patients with benign prostatic hyperplasia （BPH） were evaluated with urodynamics. All the patients were adopted to IPSS evaluation and the maximum-flow rate between preoperation and postoperation. Results：Of the 67 cases who underment the pressure-flow studies,65 cases were found in bladder outlet obstruction （BOO）,2 cases were suspicious. 65 cases with BOO were performed transurethral bipolar plasmakinetie. The changes of IPSS score and the maximum-flow rate had a significant difference postoperatively （ P〈0.05）. But there was no correlation in the types of detrusor function between preoperration and postoperation （ P〉0.05）. Conclusion：Currently pressure-flow study is the only method and gold standard for diagnosis of BOO. The urinary dynamics test is valuable to the assessment of applications and the curative effect.
