Application of low-pressure washing in the minimally invasive percutaneous renal lithotripsy

Objective To explore the application value of low pressure flushing in minimally invasive percutaneous nephrolithotomy lithotripsy.Methods Clinical data of 38 patients,who adopted the low pressure flushing therapy for curing the renal or upper ureteral calculi in the percutaneous nephrostolithotomy lithotripsy were retrospectively arakyzed.Results Aming 38 patients after operation,stone-free rate of stage 1 was obtained in 25 cases and the stones were completely removed after secondary operation in 2 cases.5 patients had partial residual stones and two cases were most of the residual stones.The mean operation time was 1 ～ 2.5h.The average duration of hospitalization was 8d.There were no intraoperative and postoperative complications,such as the spread of infection due to the surgery.Conclusion The low pressure flushing could improve clinical efficacy of percutaneous nephrostolithotomy lithotripsy and it had high security.
