目的 研究小儿先天性肾盂输尿管连接部梗阻 (UPJO)的腔内泌尿外科处理的可行性与疗效。 方法 2 0 0 0年 1月～ 2 0 0 2年 12月利用逆行气囊扩张、经皮肾顺行电刀与钬激光内切开两种方法 ,治疗 5～ 14岁UPJO患儿 2 2例 ,逆行气囊扩张 14例 ,电刀与钬激光内切开 8例。 结果 术后随访 3～ 2 6月 ,总有效率为 86 % (19/ 2 2 )。其中 1例顺行电刀内切开疗效不明显 ,改开放手术证实为UPJ异位血管压迫 ;2例气囊扩张 2次后疗效不明显 ,经顺行电刀与钬激光内切开。除经皮肾顺行电刀与钬激光内切开 8例患儿 ,术后 1～ 2d有轻微发热与患侧腹痛外 ,其余未出现并发症。 结论 腔内技术治疗小儿UPJO安全有效
Objective To study the feasibility and efficacy of endovascular treatment of pediatric congenital ureteropelvic junction obstruction (UPJO). Methods From January 2000 to December 2002, two methods of retrograde balloon dilatation, percutaneous nephrectomy and holmium laser were used to treat 22 cases of children aged 5-14 years with UPJO, Retrograde balloon expansion in 14 cases, electrotome and holmium laser in 8 cases. Results All the patients were followed up for 3 ~ 2 months, the total effective rate was 86% (19/2 2). Among them, the curative effect was not obvious in 1 case of radical electric knife incision, which was confirmed by UPJ ectopic vascular compression in 2 cases. The curative effect of 2 cases of balloon dilatation was insignificant, and was interrupted by electric knife and holmium laser. In addition to percutaneous renal electric knife and holmium laser incision in 8 cases of children, 1 ~ 2d postoperative mild fever and ipsilateral abdominal pain, the rest did not appear complications. Conclusion Endovascular treatment of children UPJO safe and effective
