Objective: To introduce a urodynamic classification of male patients with symptoms of overactive bladder (OAB) and discuss its clinical significance in practice.
Methods: From January 2015 to January 2017, there were 181 male patients from Peking University People's Hospital who were diagnosed clinically with OAB and underwent preoperative urodynamic test. Finally 126 male patients were enrolled in the research. Male OAB patients could be stratified into four groups based on the chief complaints (whether or not presenting urgency) and the results of urodynamic test (whether or not presenting detrusor overactivity and the ability to stop the involuntary contraction). The contents of this follow-up study included the basic information, the preoperative and postoperative scores of the OAB symptom score (OABSS), the preoperative and postoperative scores of the international prostate symptom score (IPSS), and the amount of the concomitant diseases.
Results: According to the classification, the amounts of the four types of OAB patients were 32 (25.40%) for type I, 27 (21.43%) for type II, 59 (46.83%) for type III, and 8 (6.35%) for type IV, respectively. The data of their heights showed no statistical significance (P>0.05). The ages, weights and the amount of the concomitant diseases of type IV were obviously higher than those of the other three types (P<0.05). And the ages, weights and the amount of the concomitant diseases of the other three types had shown no statistical significance (P>0.05). The improvement of the OABSS and IPSS scores of the type IV were obviously inferior to the other three types (P<0.05). The improvements of the OABSS and IPSS scores of type III were obviously higher than those of the other three (P<0.05). The discrepancy of the OABSS and IPSS scores of type I and type II had shown no statistical significance (P>0.05).
Conclusion: Type IV has the worst outcome and type III has the best among the four types of OAB. And this classification system will certainly have a profound significance in guiding and directing our clinical diagnosis and treatments, and evaluating the prognosis of the patients with OAB.
目的: 介绍男性膀胱过度活动症(overactive bladder,OAB)的尿动学分型并探究其临床疗效的差异。
方法: 收集2015年1月至2017年1月北京大学人民医院泌尿外科诊断为OAB并且接受尿动力学检查的男性患者共126例,根据患者的主诉(是否可感知尿急)及尿动力学检查结果(是否有逼尿肌过度活动和终止不自主收缩的能力)将膀胱过度活动症分为四型,分析患者的基本信息、伴随疾病情况、治疗前后的OAB症状评分表(OAB symptom score,OABSS)以及国际前列腺症状评分(international prostate symptom score,IPSS)是否存在差异。
结果: 根据分型方法,Ⅰ型32例(25.40%),Ⅱ型27例(21.43%),Ⅲ型59例(46.83%),Ⅳ型8例(6.35%),四型患者的身高差异无统计学意义(P>0.05),Ⅳ型患者的年龄、体质量、伴随疾病数目显著大于其余三型,差异有统计学意义(P<0.05),Ⅰ、Ⅱ、Ⅲ型患者的年龄、体质量、伴随疾病数目的差异无统计学意义(P>0.05),Ⅳ型患者治疗前后OABSS和IPSS量表差值显著小于其余三型,差异有统计学意义(P<0.05),Ⅲ型患者治疗前后OABSS和IPSS量表差值显著大于其余三型,差异有统计学意义(P<0.05),Ⅰ型和Ⅱ型患者治疗前后OABSS和IPSS量表差值的差异无统计学意义(P>0.05)。
结论: 在四型男性OAB患者中,Ⅲ型治疗效果最好,Ⅳ型治疗效果最差,此分型方法对男性OAB的个体化诊疗以及指导预后具有重要意义。
