超微通道结合组合式输尿管软镜治疗小儿肾多发结石的临床应用

Flexible ureteroscope combined with ultramini nephrostomy tract for the treatment of multiply renal calculi in pediatric patients

目的观察超微通道结合组合式输尿管软镜治疗小儿多发肾结石的临床效果。方法20例肾多发结石患儿（年龄≤7岁），于该院住院行超微通道结合组合式输尿管软镜碎石术。结果采用超微通道输尿管软镜碎石治疗小儿多发肾结石。术后血红蛋白下降率无明显变化。无需输血，手术前后肾功能变化差异无统计学意义。术后平均住院时间2 d，术后1个月随诊，根据患儿术前结石性质选择超声、尿路平片或泌尿系CT评估碎石效果，结石清石率达95%，术后随访6个月～1年，所有患儿均无远期并发症。结论组合式输尿管软镜超微通道治疗婴幼儿多发肾结石安全、有效。

ObjectiveTo evaluate the efficacy and safety of flexible ureteroscope combined with ultramini nephrostomy tract for the treatment of mutiply renal calculi in pediatric patients. Methods20 cases of children with multiply renal calculi （age ≤ 7 years old）, underwent flexible ureteroscope combined with ultramini nephrostomy tract lithotripsy. ResultsFlexible ureteroscope combined with ultramini nephrostomy tract calculi. Postoperative hemoglobin decline was no significant change. Children do not need a blood transfusion, creatinine, blood urea nitrogen and CRP were no significant differences in change. The mean postoperative hospital stay was two days, followed up for 6 months to 1 year, all patients had no long-term complications. ConclusionFlexible ureteroscope combined with ultramini nephrostomy tract for the treatment of multiply renal calculi in pediatric patients is an effective and safety method, can shorter hospital stay.
