目的探讨B超引导经皮肾镜取石术治疗上尿路结石的临床疗效和安全性。方法选择2009年9月—2012年12月上尿路结石患者87例,采用B超引导,穿刺建立皮肾通道,采用双频双脉冲激光机碎石。结果一期取石79例,二期取石8例。平均手术时间85 min,术中出血量25~55 ml85例无需输血,术中出血较多2例分别输血400 ml。平均肾造瘘管留置时间7d,平均住院时间7 d。术后发热5例,造瘘口疼痛4例,术后感染3例,经抗生素抗感染治疗均转为正常。结论 B超引导经皮肾镜取石术治疗上尿路结石高效、安全、并发症少,值得推广。
Objective To investigate the clinical efficacy and safety of B-guided percutaneous nephrolithotomy in the treatment of upper urinary tract calculi. Methods Seventy-eight patients with upper urinary tract calculi from September 2009 to December 2012 were selected. B-ultrasonography was used to establish the renal access and the dual-frequency dual-pulse laser lithotripsy was used. Results A stone in 79 cases, two stone in 8 cases. The average operation time was 85 min. The intraoperative blood loss was 25-55 ml. There was no need for blood transfusion in 85 cases, and the blood loss in the two cases was more than 400 ml. The average renal fistula indwelling time 7d, the average length of stay 7d. Postoperative fever in 5 cases, fistula pain in 4 cases, postoperative infection in 3 cases, the anti-infective antibiotic treatment were transferred to normal. Conclusion B-guided percutaneous nephrolithotomy lithotomy in the treatment of upper urinary tract stones with high efficiency, safety, fewer complications, it is worth promoting.
