研究概览
详细说明
本研究设计为单盲、随机、平行、主动对照试验。 尿动力学 DO 确诊患者被随机分配接受 onabotulinumtoxinA 100 U(BoNT-A,Allergan,Irvine,California,USA)注射,该药物用生理盐水重新配制成 10 ml 用于尿道上皮下注射,三组中的一组使用以下注射次数: (A) 100 U 10ml注射,每次注射1.0ml,膀胱体共注射10次 (B) 100 U 10ml,每次注射0.5ml,膀胱体共注射20次, (C) 100 U 10ml,每次注射0.25ml,膀胱体共注射40次。 该试验使用置换块随机化。 所有治疗均在基线和 3 个月时的主要终点进行评估。
纳入标准是任何性别的患者,年龄在 20 岁或以上,具有尿动力学 DO 和至少一次尿急发作(尿急严重程度量表,USS≥2)或每天 3 天排尿日记中记录的 UUI。 排除神经源性膀胱、尿动力学证实的膀胱出口梗阻、既往盆腔手术、止尿失禁手术或尿路感染(UTI,尿液分析中白细胞(WBC)> 10 /高倍视野(HPF))的患者。 在随机化之前获得所有患者的知情同意。 本研究应获得医院机构审查委员会和伦理委员会的批准。
所有患者在被纳入该试验之前均已通过行为矫正进行管理,并接受了一定数量的抗毒蕈碱药物治疗超过 4 周。 在筛选当天停用抗毒蕈碱药以消除剩余的作用并获得可能反映真实膀胱状况的排尿日记。
手术记录中未记录每位患者的注射方法,控制结果测量的研究护士对治疗分配不知情。 所有手术均在手术室静脉全身麻醉下经尿道进行。 onabotulinumtoxinA 治疗前 1 周停用抗凝剂。 膀胱容积保持在100-150ml,注射时避开血管。 一个留置的 Foley 导尿管被放置在膀胱中过夜,患者第二天早上出院。 术后给予广谱预防性抗生素 3 天。 建议发生急性尿潴留 (AUR) 或 PVR 体积大于 250 毫升的患者定期进行 CIC 以排空膀胱。 患者在门诊接受长达 24 个月的定期监测,直到症状恢复到基线水平。
在基线、3 个月和 6 个月时常规进行视频尿动力学研究,以测量尿动力学变量和检测膀胱输尿管反流。 测量的尿动力学变量包括:最大流速 (Qmax)、PVR、膀胱膀胱容量 (CBC)、Qmax 时的逼尿肌压力 (Pdet) 和排尿效率 (VE)。 视频尿动力学研究的程序和定义符合国际节制协会的建议。
