METHODS: 76 patients with PCNL were randomly divided into two groups, each with a total of 38 cases. Group A was treated with CREATE combined with Cyberwand double probe ultrasound lithotripsy, and B group was treated with ClearPetra negative pressure stone sheath combined with pneumatic lithotripsy and/or holmium laser lithotripsy. RESULTS: All patients were treated with 1 stage operation successfully. Compared with group A, group B had a higher rate of stone removal (84.2% vs, 63.1%, P=0.037). There was no significant difference in stone clearance (94.4% vs, 86.8%, P=0.235). The operation time of B group was 56.3±19.83 min, significantly shorter than that of group A at 70.4±14.83 min (). The complication rate of B group was 15.8%, which was lower than that of group A (P=0.035). Postoperative fever (>38.5°C) was found in group B of 5 cases, group A of 8 cases. All were treated with anti infection therapy. There was no blood transfusion in group A, 1 cases in group B required transfusion. One patients of group A with infection, who discharged with nephrotomy tube, recovered one months after the procedure. CONCLUSIONS: percutaneous nephrolithotomy combined with ClearPetra negative pressure clear stone sheath is a simple, safe, effective, economical and practical method for the treatment of obstructive calculous pyonephrosis.
