To evaluate the therapeutic effect of minimally invasive percutaneous nephrolithotomy (MPCNL) under ultrasonic and X-ray guidance in the treatment of complicated renal calculi.
A retrospective analysis was conducted among 36 patients undergoing MPCNL under ultrasonic and X-ray guidance for complicated renal calculi. The general clinical data, stone size, operative time, blood loss, complications and stone clearance rate were analyzed.
Double working channel was established accurately under ultrasonic and X-ray guidance in the 36 cases. The stone clearance rate in one treatment session was 80.56%, with an average operation time of 100 min and a mean hospital stay of 13.5 days (13-15 days) after operation. A second lithotripsy was performed in 5 cases and no residual renal calculi were found 1 month after the operation. Sixteen out of the 18 patients with preoperative elevation of serum creatinine recovered normal creatinine level after the operation.
MPCNL under ultrasonic and X-ray guidance is safe and effective for treatment of complicated renal calculi and is associated with few postoperative complications.
评估超声与X线引导下微创经皮肾镜取石术（MPCNL）治疗复杂性肾结石的疗效。
对36例在超声与X线引导下接受MPCNL治疗复杂性肾结石的患者进行回顾性分析。分析患者的一般临床资料、结石大小、手术时间、出血量、并发症及结石清除率。
36例患者均在超声与X线引导下准确建立双工作通道。单次治疗结石清除率为80.56%，平均手术时间为100分钟，术后平均住院时间为13.5天（13 - 15天）。5例患者进行了二次碎石，术后1个月未发现残余肾结石。18例术前血清肌酐升高的患者中，16例术后肌酐水平恢复正常。
超声与X线引导下的MPCNL治疗复杂性肾结石安全有效，术后并发症少。
