ABSTRACT：Objective To compare theclinical eficacy of mini percutaneous nephrolithotomy （mPCNL）and super mini percutaneous nephrolithotomy（SMP） in the treatment of single pediatric renal pelvis stones with CT value ，to providereference for the diagnosis and treatmentof children with such low-density stones.MethodsTheclinical dataof 74 children with single renal pelvis stones （1.0-2.5cm in size，CT value ⩽800HU ） treated in our hospital during Jan.2ol5 and Dec.202l were retrospectively，with the subjects divided into mPCNL group （ n=39 ）and SMP group（ n=35 ）based on the surgicalmethods.Theoperation time，decrease inhemoglobin 2hoursaftersurgeryhospital tay，stoneclearancerate，tubele rate，and theincidence ofcomplications（fever，mild renal pelvis injury）were compared betwen thetwo groups.ResultsThe operation time [（45.5±20.1） min vs. （59.8±13.6） ）min， P<0.001] and average hospital stay [（7.1±1.4） d ′s.（11.1±2.6） d， P<0.001] were shorter in the SMP group than in the mPCNL group，while the tubeless rate （68.6% vs. 10.3% P<0.001 ） was higher.There were no significant diferences inthe hemoglobin 2hours aftersurgeryand stoneclearancerateatl month after surgery between the two groups （ P>0.05） . No blood transfusion was required in either group.Fever ） occured in1caseand mildrenal pelvis perforation occurred in2 cases in the SMP group，while feveroccurred in cases and mildrenalpelvis perforation occurred in 3cases in the mPCNL group，with no significant diference between the two groups （ 8.6% vs. 12.8% P=0.556 ）. ConclusionThe mPCNL and SMP have comparable efficacy in the treatment of single pediatric renal pelvis stones with CT value ⩽800 HU，but SMP has advantages of shorter operation time，shorter average hospital stay，and higher tubeless rate.
