目的:探讨气膀胱腹腔镜治疗儿童下尿路多发磁珠异物的疗效。方法:2019年1～11月对武汉儿童医院泌尿外科就诊的3例下尿路磁珠异物患儿施行下腹部三通道气膀胱腹腔镜下异物取出术。对取出磁珠数量、有无磁珠残留、手术时间、手术出血量、术后是否有尿外渗及直肠损伤、术后疼痛评分、术后住院时间、手术切口家长满意度等指标进行分析。结果:3例患儿均顺利完成手术，分别取出31颗、52颗、38颗磁珠，并且均无磁珠残留，平均手术时间60 min，平均出血量4 ml，术后4 h平均疼痛评分4.2分，术后12 h平均疼痛评分1.6分，术后平均住院日5.5 d，均未出现尿外渗、直肠损伤等并发症。术后门诊随访1～6个月，3例患儿均无血尿、泌尿道感染及膀胱憩室等并发症，伤口美观无瘢痕。结论:气膀胱腹腔镜手术治疗儿童下尿路磁珠异物损伤小，操作简便，效果好，值得临床推广应用。“,”Objective:To evaluate the efficacy of gas-bladder laparoscopy for the treatment of magnetic beads in the lower urinary tract of children.Methods:From January to November 2019, 3 children with magnetic bead foreign bodies in the lower urinary tract who visited the Department of Urology, Wuhan Children's Hospital underwent three-channel pneumovesical laparoscopic removal of foreign body removal in the lower urinary tract. The number of removed beads, presence or absence of residual beads, operative durationon time, intraoperative volume of blood loss, postoperative urinary extravasation, rectal injury, postoperative pain score, postoperative hospital stay, and parental satisfaction with the surgical incision were analyzed.Results:All patients (n = 3) finished procedures successfully. And 31, 52 and 38 magnetic beads were removed entirely without residual magnetic beads. The average operative surgical duration was 60 min, the average hemorrhagic volume was 4 ml, the average pain score was 4.2 points at 4 h after operation, and 1.6 points at 12 h after operation, and the average postoperative hospital stay was 5.5 days. None of them had such complications like as urinary extravasation or rectal injury. During a follow-up period of for 1-6 months, none of the 3 patients had ccomplications as hematuria, urinary tract infection or bladder diverticulum. The wounds healed well without scar.Conclusions:The satisfactory outcomes may be achieved for gas-bladder laparoscopic removal of magnetic beads in lower urinary tract of children. And this mini-invasive procedure operation which has less damage, allows an easier operation with an excellent efficacy. A wider clinical popularization is recommended and better effect deserves being generalized in the clinic.
