目的探讨经皮肾镜取石术(PCNL)应用超声碎石清石系统治疗上尿路感染性结石的临床疗效和安全性。方法回顾性分析53例PCNL应用超声碎石清石治疗上尿路感染性结石的患者资料。结果 PCNL术后结石完全清除50例(94.4%),行Ⅱ期PCNL取石2例(3.8%),联合体外震动波碎石术(ESWL)1例(1.9%)。术中无患者输血,平均住院时间8d,5例(9.4%)出现术后低热,全组病例均未出现严重出血、感染性休克、肾动静脉瘘及邻近器官损伤等并发症。结论 PCNL联合超声碎石清石系统是治疗上尿路感染性结石安全、有效。
Objective To investigate the clinical efficacy and safety of percutaneous nephrolithotomy (PCNL) in the treatment of infectious upper urinary tract stones with ultrasonic lithotripsy. Methods A retrospective analysis of 53 cases of PCNL application of ultrasonic lithotripsy for upper urinary tract infection in patients with stone. Results Fifty patients (94.4%) had complete removal of calculus after operation for PCNL, two patients (3.8%) got PCNL in stage II, and one patient (1.9%) received ESWL in one patient. No blood transfusions occurred in patients during operation. The average length of hospital stay was 8 days. Five patients (9.4%) developed postoperative fever. No severe bleeding, septic shock, renal arteriovenous fistula or adjacent organ injury occurred in all the cases. Conclusion PCNL combined with ultrasonic lithotripsy is safe and effective in treating upper urinary tract infection stones.
