ABSTRACT

Objective: To explore the effect of therapeutic application of pneumatic ballistic lithotripsy under percutaneous nephroscope ultrasound and holmium laser lithotripsy for complex kidney stone. Methods: 124 patients with complex renal calculus were selected and divided into observation group (62 cases) and control group (62 cases) as randomly number table. The patients of observation group were cured by pneumatic ballistic lithotripsy under percutaneous nephroscope ultrasound while patients of control group were cured by holmium laser lithotripsy. A series of correlative indicators, such as some correlative indexes in during and post operation, complication situation of post operation and kidney function, were compared. Results:The differences about bleeding volume during operation and postoperative hospital stay between the two groups were significant (t=12.475, t=7.659, P<0.05). For clearance rate of calculus and incidence of complication, the differences between the two groups were significant (x2=6.048, x2=7.159, P<0.05). And the differences of separation index of renal pelvis collective system, creatinine and urea nitrogen post treatment between the two groups also were significant (t=8.529, t=7.058, t=10.596, P<0.05). Conclusion: Comparing with the traditional holmium laser lithotripsy, the clinical better effect of pneumatic ballistic lithotripsy under percutaneous nephroscope ultrasound for complex renal calculi is significant. Its series of advantages, such as shorter operation time, faster recovery, safer and reliable for patients and lower incidence of postoperative complication and so on, can effectively relieve the renal function for patients.
