The clinical application of endoscopic minimally percutaneous nephrolithotomy under the color Doppler ultrasound guided

Objective: To evaluate the clinical value of endoscopic minimally percutaneous nephrolithotomy(mini percutancous nephrolithotomy,MPCNL) with color Doppler ultrasound guided.Methods: Using ultrasound-guided,to establish of channels through the skin to the kidney,and real-time guided puncture needle to the parts of the renal pelvis and stones,and then applied nephrolithotomy holmium laser lithotripsy ureteral stones,nephrolithiasis.Results: The patients in 18 cases of percutaneous renal channel in the lower renal calices established in 14 cases,and middle renal calices established in 4 cases;one channel successfully established in 17 cases,the success rate was 94.45%(17/18),secondary 1 case to establish a successful puncture channel;by the nephrolithiasis lithotripsy in 16 cases successfully,clearance rate was 88.9%(16/18),2 cases because of severe adhesions and left residual calyceal stones left residual rate was 11.1%(2/18),18 cases were not thoracic and abdominal organ damage,kidney penetrating injury,bleeding and other severe complications.Conclusion: The treatment of the MPCNL under the color doppler ultrasound guided appears to be positioning accuracy,efficiency and security,no radiation,and surgery treatment can be monitored,it is to ensure MPCNL key to successful operation,and has very important clinical value.
