title: [Comparison of Cyberwand dual probe lithotriptor and Swiss lithoclast master in ultrasonically guided percutaneous nephrolithotomy for renal staghorn calculi].
abstract: OBJECTIVE
  To evaluate and compare the efficiency and safety of Cyberwand dual probe lithotriptor and Swiss lithoclast master in percutaneous nephrolithotomy for renal staghorn calculi.
  
  
  METHODS
  A total of 138 patients with renal staghorn calculi were divided randomly into a Cyberwand dual probe lithotripter group (Group A, n=71) and a Swiss lithoclast master group(Group B, n=67). The data for operative time, blood loss volume, one-stage calculus clearance rate, hospitalization time, cost of hospitalization and complication in the two groups were collected and compared.
  
  
  RESULTS
  The renal access was established successfully and the one-stage percutaneous nephrolithotomy (PCNL) was performed in the 2 groups. There was no significant difference in the size of stones, the age of patients and the complications between the 2 groups before the operations. Intraoperative gravel time in the Group A was significantly shorter than that in the Group B (77.14±21.39 vs 84.25±20.62, P=0.049). There was no significant difference in the one-staged stone clearance rate, blood loss volume in the operation between the 2 groups. The one-staged stone clearance rate in the 2 groups were 67.6% (48/71) and 70.1% (47/67) respectively, with no significant difference (P=0.854).
  
  
  CONCLUSIONS
  Two lithotrities were safe and efficient for renal staghorn calculi. But comparing with Swiss lithoclast master, Cyberwand dual probe lithotriptor is more efficient and convenient.
