【摘要】 为了研究前列腺增生症（ＢＰＨ）病人的逼尿肌功能改变，对４２例ＢＰＨ病人进行了尿动力学研究。结果表明：８例逼尿肌代偿（ＣＣＤ）、９例逼尿肌无力（ＡＣＤ）、１５例逼尿肌不稳定（ＤＩ），ＤＩ组病人术后出现明显的膀胱刺激症状及膀胱痉挛，服用异博定、普鲁苯辛、安定和泌尿灵四联药物后症状明显减轻。认为ＢＰＨ患者除膀胱逼尿肌发生代偿性改变外，还发生逼尿肌不稳定性收缩和逼尿肌收缩无力等改变。术前尿动力学检查可以指导临床治疗，对伴有ＤＩ者术前服用钙离子通道阻滞剂为主的四联药物，可以减轻膀胱刺激症状。更多还原

【Abstract】 Urodynamic study was carried out in 42 benign prostatic hyperplasia patients to investigate the changes in bladder detrusor function. The urodynamic findings were classified as “detrusor instablility(DI)”, acontractile detrusor(ACD), and “compensative contraction detrusor(CCD)". Serious irritative symptom of the bladder after surgical relief of the prostatic obstruction would appear in patients with detrusor instability. The symptoms could be alleviated after verapamil administration. Detrusor dysfunction such as DI、CCD and ACD might occur in BPH. It was stressed that urodynamic study of the detrusor function before operation was important to guide the treatment of BPH.更多还原
