Pneumatic and ultrasonic lithotripsy treatment of staghorn renal stone in percutaneous nephroscopic(report of 34 cases)

Objective To evaluate and study the efficacy and safety of combination ultrasonic and pneumatic lithotripsy treatment of staghorn renal stone in percutaneous nephroscopic.Methods From January 2008 to January 2009,34 patients with staghorn renal stone received combination ultrasonic and pneumatic lithotripsy by F20.8 nephroscopic at our institute.The stone-free rate and complication were assessed,and the clinical data were retrospectively analysed.Results In 34 cases,Total stone clearance amounted to 88.2%,obstruction unchain amounted to 100%.The first PNL stone clearance amounted to 64.7%.The operation time was 82 to 180 minutes,with an average of 113 minutes.The blood loss was 80 to 500 ml,with an average of 160 ml.1 patient required 4? RBC transfusion after operation.The duration of hospitalization was 7-15 days with an average of 9.6 days.Urinary tract infection(38.5℃,3days) after operation was seen in 23 patie nts,no severe infection was observed.12 patients kidneys had one or more residual-stones 0.8-2.5 cm,9 patients under went second operation of PNL.The second PNL stone clearance amounted to 88.9%.Follow-up of 1 to 6 months'duration for 28 cases showed good results.Without recurrence.Conclusion The pneumatic and ultrasonic combination lithotripsy in percutaneous nephrolithotomy treatment of staghorn renal stone is a highly efficient procedure and provides safe and fast stone removal
