Objective: To evaluate the clinical value of ultrasound-guided and fluoroscopy in percutaneous nephrostomy (PNT). Methods: By ultrasound-guided and fluoroscopy percutaneous placement of nephrostomy catheters were performed in 53 patients with hydronephrosis or pyonephrosis by using Seldinger technique. Results: Fifty-eight kidneys in 53 patients were punctured by percutaneous way, including 30 right kidneys, 22 left kidneys and 3 bilateral kidneys. Fifty-six kidneys (96.6％, 56/58) were successfully puncture at first attempt. The punctures in contralateral kidneys were performed in 2 patients because of the failure of first attempt. Fifty-six nephrostomy catheters (100％, 56/56) were successfully implanted by fluoroscopy-guidance. The improvement of renal function was obvious after operation, and no severe complications occurred. Conclusion: PNT by ultrasound-guided and fluoroscopy is a fast, safe, microinvasive and effective procedure for patients with obstructive uropathy, and this method is worth generalizing and applying.%目的:评价超声与透视相结合在经皮肾穿刺造瘘术中的应用价值.方法:对53例不同原因所致的肾盂积水或积脓患者,采用在超声与透视相结合引导下经皮肾穿刺造瘘术.结果:本组53例患者共穿刺58个肾脏,其中右肾33例,左肾25例,其中同时行双侧穿刺3例.其中一次穿刺成功率为96.6%(56/58),2例失败而行对侧肾盂穿刺.共留置造瘘引流管56枚,造瘘引流管留置成功率100%(56/56).术后患者肾脏功能改善明显,全部病例均无严重并发症发生.结论:超声与透视相结合行经皮肾穿刺造瘘快速、安全、微创、有效且并发症少,值得推广应用.
