目的 应用尿动力学检查评测前列腺增生症 (BPH)患者膀胱功能。方法 对85例BPH患者进行了尿动力学检查及分析。结果 不稳定膀胱 (DI)43例 (50.6 % ) ,逼尿肌活动低下 (DUA)15例 (17.6 % ) ,膀胱功能正常和逼尿肌功能亢进 (其他 )27例 (31.8% ) ;其中年龄<60岁、60～79岁、≥80岁者DI的发生率分别为38.5%、54.9%和62.5% ,DUA的发生率分别为7.7 %、21.6%和25.0% ;DI、DUA和其他三组间前列腺症状评分的差别无显著性意义(P>0.05) ,而年龄、膀胱最大容量和膀胱顺应性的差别有显著性意义 (均P<0.05)。26例 (30.6% )出现顺应性降低 ,其中19例伴有DI。结论 尿动力学检查能明确BPH患者逼尿肌顺应性和收缩功能 ,可减少治疗的盲目性 ,对合理选择手术适应证、预测和提高手术疗效具有重要意义
Objective To evaluate urinary bladder function in patients with benign prostatic hyperplasia (BPH). Methods Eighty-five patients with BPH underwent urodynamic examination and analysis. Results In 43 cases (50.6%) with unstable bladder (DI), 15 cases (17.6%) with detrusor hypoplasia (DUA), 27 cases (31.8%) with normal bladder function and detrusor hyperfunction (others) The incidence of DI in patients aged 60 years, 60-79 years and ≥80 years were 38.5%, 54.9% and 62.5%, respectively. The incidence of DUA was 7.7%, 21.6% and 25.0% respectively. DI, DUA and other three groups There was no significant difference between the two groups (P> 0.05), but there was significant difference between age, bladder maximum capacity and bladder compliance (all P <0.05). Twenty-six patients (30.6%) had decreased compliance, of which 19 had DI. Conclusion Urodynamic examination can confirm the detrusor compliance and systolic function in patients with BPH and reduce the blindness of treatment, which is of great significance for the rational selection of surgical indications, prediction and improvement of operative efficacy
