目的探讨超声引导下经皮穿刺肾脏造瘘对改善肾后性梗阻患者肾功能的临床价值。方法 28例患者(30个肾脏)在超声引导下,采用一步法将7F～8F猪尾巴导管放置于扩张的肾盂内,引流减压。结果 28例患者30个肾脏,放置导管成30个,功率为100%,无严重并发症。结论实时超声引导下经皮穿刺肾脏造瘘术的成功率高,创伤小、安全、有效、可靠、并发症少,对改善肾后性梗阻引起的肾功能衰竭具有重要的临床意义。
Objective To investigate the clinical value of ultrasound-guided percutaneous nephrostomy in improving renal function in patients with post-renal obstruction. Methods 28 patients (30 kidneys) under the guidance of ultrasound, using a one-step approach 7F ~ 8F pig tail catheter placed in the dilated renal pelvis, drainage decompression. Results 28 patients with 30 kidneys placed 30 catheters, power was 100%, no serious complications. Conclusion The success rate of percutaneous nephrostomy guided by real-time ultrasound is small, safe, effective, reliable and has few complications. It is of great clinical significance for improving renal failure caused by renal obstruction.
