Clinical Efficacy Comparison Of Standard Channel And Super-mini Percutaneous Nephrolithotomy For The Treatment Of Renal Calculi

Objectives:This study aims to explore the safety and efficacy of the standard channel percutaneous nephrolithotomy and the super-min percutaneous nephrolithotomy by comparing the clinical indicators,so as to provide a reference in the future.Methods:From November 2016 to January 2019,60 renal calculi patients met the inclusion criteria in the Department of Urology,Qinghai Provincial People’s Hospital.According to the general condition of the patients and the treatment,the patients were divided into the standard channel percutaneous nephrolithotomy group(30 cases)and the super-mini percutaneous nephrolithotomy group(30 cases).The operation time,intraoperative blood loss,stone size,postoperative hospitalization time,hospitalization cost,postoperative complications,stone-free rate and other clinical indicators were retrospectively analyzed.Results:All patients of the both groups underwent one-stage single-channel puncture approach and successfully completed the operation.The average operation time in the SPCNL group was(86.3±10.5)min,the mean intraoperative blood loss was(59.5±17.6)ml,the average operation time in the SMPCNL group was(102.3±8.6)min,and the mean intraoperative blood loss was(32.8±10.6)ml,the differences were statistically significant in operation time and intraoperative blood loss between the two groups(p<0.05).There were no significant differences in stone size,postoperative hospitalization time,hospitalization cost,postoperative complications and stone-free rate(p>0.05).Conclusions:SPCNL and SMPCNL are technically feasible,safe and effective in the treatment of renal calculi.SPCNL has the advantage of shorter mean operation time,and less mean intraoperative blood loss.This study did not find significant differences in other indicators.As SMPCNL is a newly emerging technology in China in recent years,it needs further exploration in clinical application.Therefore,SMPCNL technology is a supplement to SPCNL,and both of them play an important role in the treatment of renal calculi.
