小儿后腹腔镜下离断性肾盂成形术

目的 探讨小儿后腹腔镜下离断性肾盂成形术的临床效果.方法 肾盂输尿管连接部梗阻(UPJO)患儿24例.平均年龄7(3～14)岁.经B超、IVU、CT,磁共振水成像检查临床确诊,轻度肾积水4例、中度10例、重度10例.均采用后腹腔镜下离断性肾盂成形术治疗.结果 24例手术均获成功,无中转开放手术.手术时间平均180(150～200)min,出血量平均60(40～100)ml,术后住院平均7(5～9)d.随访平均14(6～24)个月,吻合口无狭窄,肾积水消失18例,肾积水明显减轻6例.结论 后腹腔镜下离断性肾盂成形术治疗小儿 UPJO安全、有效,可以替代开放手术.

Retroperitoneal laparoscopic dismembered pyeloplasty in pediatric ureteropelvic junction obstruction

Objective To discuss the efficacy of retroperitoneal laparoscopic dismembered pyeloplasty for pediatric ureteropelvic junction obstruction(UPJO). Methods Retroperitoneal laparoscopic dismembered pyeloplasty was performed on 24 patients with UPJO.The age of the patients ranged from 3 to 14 years(mean,7 years).The diagnosis was set up by ultrasonography,IVU,CT or magnetic resonance urography.All the patients had hydronephrosis,with 4 cases mild,10 cases moderate and 10 severe ones. Results All operations were completed laparoscopieally,without conversions to open surgery during operation.The mean operative time was 180 min(range 150 to 200).The mean blood loss was 60 ml(range 40 to 100)and the mean postoperative hospital stay was 7 d (range 5 to 9).All 24 patients were followed-up for 6 to 24 months(mean,1 4 months).There was no stricture at UPJ.Eighteen patients had complete resolution of hydronephrosis and 6 patients showed obvious alleviation in hydronephrosis. Conclusion Retroperitoneal laparoseopie dismembered pyeloplasty could be a mini-invasive,safe,and effective procedure for the treatment of UPJO in pediatric patients.
