The Treatment of Upper Urinary Calculus with Minimally Invasive Percutaneous Nephrolithotomy Under the Guidance of Asynchronous 16-slice Spiral CT Combined B-ultrasound Localization

Objective： To evaluate the feasibility and the clinical outcomes of minimally invasive percutaneous nephrolithotomy（MPCNL） with asynchronous 16-slice spiral CT combined B-ultrasound localization to establish percutaneous access in the treatment of upper urinary calculus.Method： 150 cases of unilateral kidney or（and） ureteral stones underwere MPCNL under the guidance of asynchronous 16-slice spiral CT combined B-ultrasound localization were retrospectively analyzed.Result：150 cases established percutaneous access successfully in first operation,and the overrall rate of fragmentation for upper urinary calculus was 98%.The stage 2 lithotripsy was carried in 3 cases.The mean operative time was 88min;mean blood loss was 50mL;Conversion to open surgery does not appear;No perioperative severe complications such as hemorrhoea and blood transfusion,ureteral perforation,pneumatothorax and Pleural effusion、ascites,trauma of abdominal organ occurred.Conclusion：MPCNL with asynchronous 16-slice spiral CT combined B-ultrasound localization is a feasible,safe and highly effective therapy for the treatment of upper urinary calculus.It has high clinical Application value.
