尿动力学检查在良性前列腺增生症诊治中的应用

目的探讨尿动力学检查在良性前列腺增生症诊疗中的意义。方法对103例前列腺增生患者进行尿流率测定、残余尿量测定、充盈性膀胱测压、压力一流率同步测定、尿道压力测定，并分析检查结果。结果103患者行尿流率测定，25例不能自行排尿，78例患者最大尿流率〈15ml／s、平均尿流率〈10ml／s；逼尿肌稳定67例，逼尿肌不稳定36例；高顺应性膀胱11例，低顺应性膀胱22例，顺应性正常70例；膀胱充盈感觉减退21例，感觉增强23例，感觉正常59例；逼尿肌收缩有力78例，P／Q图显示膀胱出口梗阻66例，可疑梗阻12例，逼尿肌收缩力降低，未能排出尿液25例；103例患者均显示前列腺及功能尿道长度延长，75例患者显示膀胱颈压升高。结论尿动力学检查能正确判断患者是否有膀胱出口梗阻，还可评估膀胱逼尿肌功能，在前列腺增生症的诊断和治疗中具有重要的临床价值。

Use of urodynamics in the diagnosis and treatment of benign prostate hyperplasia

Objective To study the significance of urodynamics in the diagnosis and therapy of benign prostate hyperplasia （ BPH ）. Methods To determine uroflometry, residual urine volume, filling cystonetry,pressure -flow study, urethral pressure profile with 103 cases of BPH, and to analyze the results. Results Of 103 cases with uroflometry,25 cases without voluntary micturition, 78 cases＇ maximum flow rate（MFR） 〈 15 ml/s, average flow rate（AFR） 〈 10 ml/s. And 67 cases with detrusor stability,36 cases with detrusor instability, 11 cases with high compliance bladder, 22 cases with low compliance bladder, 70 cases with normal compliance bladder; 21 cases with filling of bladder hypoesthesia,23 cases with hyperesthesia, 59 cases with euesthesia, 78 cases with contractile detrusor. Through P/Q reveal, there were 66 cases with bladder outlet obstruction（BOO）, 12 cases were suspicious BOO, 25 cases with lower contractile detrusor and without voluntary micturition. The prostates and urethral functional lenghth of 103 cases were prolong, of 75 cases with high pressure of bladder neck. Conclusions Urodynamics test provides great value in diagnosis of BOO and important appraisal function of detrusor, and has important significance to the diagnosis and treatment of BPH.
