The Effect of Percutaneous nephrolithotomy in the Treatment of Complicated Renal Calculi under Color Doppler Ultrasound Guidance

Objective: To summarize the treatment experience of color Doppler ultrasound-guided percutaneous nephrolithotomy(PCNL), and investigate the safety and efficacy and common complication of the surgery. Methods: A retrospective analysis of 56 complex renal calculi cases`s clinical data in our hospital from July 2011-2012 August which were treated by color Doppler guided percutaneous nephrolithotomy were made. Results: The procedures of percutaneous nephrolithotomy in 56 cases were performed in 1 stage. The average operation time was(107.5 ±27.5) minutes, 24 patients were performed ultrasonic lithotripsy combined with pneumatic lithotripsy; 20 patients were performed holmium laser and ultrasound, and 10 patients were performed ultrasonic lithotripsy. The operation time of ultrasonic lithotripsy combined with pneumatic lithotripsy groups was(101.0±27.9) min, which is significant lower than holmium laser and ultrasound group(119.4±23.6) min. Stones depletion rate is 91%, No other organ injury and severe blood loss in surgery. 4 cases have severe infection and 5 cases have delayed bleeding after surgery. Conclusion: Percutaneous nephrolithotomy under the guide of color dopplar ultrasound was a safe and effective method to treat complex kidney calculus, it could also effectively avoid renal Macrovascular injury, and reduce the risk of bleeding.
