Clinical observation on establishing work tract of percutaneous nephrolithotomy by Ultrasound guidance

Objective To investigate the technique of establishing work tract of percutaneous nephrolithotomy guided by ultrasound.Methods A total 289 patients with kidney stones underwent percutaneous nephrolithotomy though working tract by ultrasound-guidance.Results The procedure of puncture was successful in 289 patients in first puncture.There was no pleural injury,abdominal organs injury,renal pelvis tearing and penetrating kidney injury. Stones clearance rate was 85.5%(247/289).Conclusion It is safe and feasible to establish percutaneous nephrolithotomy work tract using ultrasound guidance,when mastering the operation techniques.
