The comparative study of minimally invasive percutaneous nephrolithotomy lithotripsy and extracorporeal shock wave lithotripsy for upper urinary tract stones

Objective To explore and comparative analysis of minimally invasive percutaneous nephrolithotomy lithotripsy and extracorporeal shock wave lithotripsy treatment on the clinical efficacy and safety of urinary tract stones,designed to provide guidance for clinical treatment basis.Methods From January 2011 to January 2012 in our hospital,selected 80 patients with upper urinary tract stones in patients before surgery were confirmed by urinary B ultrasound,intravenous pyelogram(IVP) diagnosed ureteral stenosis and renal dysfunction.A total of 80 cases with upper urinary calculi were randomly divided into observation group(MPCNI) and the control group(ESWL),each of 40 cases.Compared two groups of stone clearance rate,operative time,complications.Results Compared with the control group,the stone clearance rate of the observation group were significantly higher than that in the control group,the difference was statistically significant(χ2 = 8.237,P 0.05).Observation group regardless of the size of stones,the operative time was significantly shorter than the control group,the difference was statistically significant(P 0.05).Complications in the number of cases of the observation group was significantly less than that of the control group(P 0.05).Conclusion Compared with extracorporeal shock wave lithotripsy,percutaneous nephrolithotomy ureteroscopy single stone clearance rate,operative time points,fewer complications,and worthy of clinical application.
