Objective:To investigate the clinical efficacy and safety of PCNL with the use of different percutaneous renal access in treatment of renal calculi.Methods:Percutaneous renal minimal access(F14~F16)or small access(F18~F20)was established randomly in 142 patients
and PCNL were performed in all patients.The clinical parameters including operative time
complication and stone-free rate were compared in the two groups.Results:The operative time of simple renal calculi were(78.3±15.6)min and(91.2± 18.2)min(P<0.01)respectively
and the stone-free rate were 90.6%and 80.0%(P>0.05)in small access group and minimal access group respectively.The operative time of complicated renal calculi were(115.3±20.1)min and(130.7±28.7)min(P<0.01)
and the stone-free rate were 76.1%and 51.7%(P<0.05)respectively.Conclusion:PCNL of small access proves to be effective and safe for treatment of renal calculi
