Pneumatic lithotripsy for treatment of complicated kidney calculi

Objective To evaluate the therapeutic efficacy in patients with complicated kidney calcule who were treated with Percutaneous Nephroscope Lithotripsy(PCNL).Methods From December 2001 to February 2003,14 patients with complicated kidney calcule were treated with PCNL.Results 13 cases could been treated by PCNL at once (92.9%).One case were delayed to treat with Lithotripsy because of pyohydroneprosis.The total stone-free rate is 71.4%(10/14) after 30 days who be cured with PCNL.Conclusion Treatment of complicated kidney calcule with PCNL has been safe,effective,less invasive,less complicate and can avoid open surgery.It is pointed out that the cruxes of successful lithotripsy were the Percutaneous Nephrotithotomy.The ureteral tents shold be placed regularly after operation.
