目的：探讨新型可控性人工肾积水在经皮肾穿刺精确定位的临床应用。方法本研究选择经皮肾碎石患者400例,随机分为2组,A组200例患者行新型可控性人工肾积水辅助装置经皮肾碎石术,B组200例患者行传统人工肾积水穿刺定位经皮肾碎石术。比较2组患者建立穿刺通道时间,术中出血量,穿刺次数。结果 A组195例患者1次建立经皮肾造瘘通道,5例患者2次穿刺定位经皮肾造瘘成功。 B组157例患者1次建立经皮肾造瘘通道,40例患者行2次或者多次穿刺定位,3例患者穿刺定位失败。 A组和B组患者的穿刺时间、术中出血量、穿刺次数分别为(1.8±0.7) min vs.(2.5±1.2) min,(112.7±51.0) mL vs.(270.2±89.3)mL,(1.1±0.2)次vs.(1.8±0.7)次。差异具有统计学意义,P<0.05。结论制备新型人工肾积水可为经皮肾穿刺造瘘提供有效引导。%Objective To explore clinical application of neotype controllability artificial nephrohydrosis in percutaneous nephrolithoto-my. Methods 400 patients with renal lithiasis or superior segment ureter lithiasis in our hospital were divided into group A and group B. 200 cases of group A received neotype controllability artifiicial nephrohydrosis;200 cases of group B received conventional artificial nephro-hydrosis. The puncture duration, amount of bleeding and times of puncture of the two groups were compared. Results 195 cases in Group A were developed renal tract for PCNL effectively,157 cases were developed renal tract for PCNL effectively in Group B. The puncture duration, amount of bleeding and times of puncture of group A and group B were respectively (1. 8 ± 0. 7) vs. (2. 5 ± 1. 2) min,(112. 7 ± 51. 0) vs. (270. 2 ± 89. 3) mL,(1. 1 ± 0. 2) vs. (1. 8 ± 0. 7) times. The differences were significant. Conclusion Neotype controllability artificial nephrohydrosis can develop renal tract for PCNL effectively.
