BACKGROUND
Gaining access into non-dilated renal collecting systems for percutaneous nephrolithotripsy, particularly in patients with prohibitive body habitus and/or scoliosis, is often challenging using conventional techniques.
OBJECTIVE
To evaluate the feasibility of cone-beam CT for percutaneous nephrostomy placement for subsequent percutaneous nephrolithotripsy in children and adolescents.
MATERIALS AND METHODS
A retrospective review of percutaneous nephrostomy revealed use of cone-beam CT and 3-D guidance in 12 percutaneous nephrostomy procedures for 9 patients between 2006 and 2015. All cone-beam CT-guided percutaneous nephrostomies were for pre-lithotripsy access and all 12 were placed in non-dilated collecting systems.
RESULTS
Technical success was 100%. There were no complications.
CONCLUSION
Cone-beam CT with 3-D guidance is a technically feasible technique for percutaneous nephrostomy in children and adolescents, specifically for nephrolithotripsy access in non-dilated collecting systems.
背景
对于经皮肾镜碎石术而言，进入未扩张的肾集合系统往往具有挑战性，尤其是对于体型特殊和/或患有脊柱侧弯的患者，使用传统技术时更是如此。
目的
评估锥形束CT在儿童和青少年经皮肾造瘘术（用于后续经皮肾镜碎石术）中的可行性。
材料与方法
对经皮肾造瘘术进行回顾性研究，结果显示在2006年至2015年间，9例患者的12例经皮肾造瘘术中使用了锥形束CT和三维引导。所有锥形束CT引导下的经皮肾造瘘术均用于碎石术前的通路建立，且所有12例均置于未扩张的集合系统中。
结果
技术成功率为100%。无并发症发生。
结论
三维引导下的锥形束CT对于儿童和青少年的经皮肾造瘘术是一种技术上可行的技术，特别是用于未扩张集合系统中的肾镜碎石术通路建立。
