应用尿动力学技术，术前确定３２例前列腺增生症（ＢＰＨ）患者有无逼尿肌不稳定。观察ＢＰＨ术后逼尿肌稳定组（Ａ组）和不稳定组（Ｂ组）患者膀胱痉挛的发生率和严重程度。结果：Ａ组的膀胱痉挛发生率（１００％）和较重膀胱痉挛的发生率（８２．４％）均显著高于Ｂ组（５３．３％和５０％，Ｐ＜０．０１）。提示逼尿肌的不稳定与术后膀痉挛密切相关
Application of urodynamic techniques, preoperative determination of 32 cases of benign prostatic hyperplasia (BPH) in patients with or without detrusor instability. To observe the incidence and severity of bladder spasm in patients with detrusor stabilization (group A) and unstable group (group B) after BPH. Results: The incidence of bladder spasm (100%) and severe bladder spasm (82.4%) in group A were significantly higher than those in group B (53.3% and 50%, P <0.01). Tip detrusor instability and bladder spasm are closely related
