| Background and Aim:Systematic evaluation of the efficacy and safety of ultra-microchannel percutaneous nephrolithotomy and ureteroscopy for the treatment of renal stones below 3 cm.Methods:Retrieving PubMed,Web of science,EmBase,China Knowledge Network,Wanfang Database and China Biomedical Database from the establishment of the database to all the randomized controlled studies or cohort studies on SMP and RIRS for the treatment of kidney stones in January 2019,Inclusion and exclusion criteria,and biased assessment of the detected literature.The extracted data were analyzed using relevant software(Rev Man 5.3,Stata 15.1),and the difference between the SMP and RIRS was evaluated using the 95% confidence interval(CI)summary mean difference(MD)or odds ratio(OR).Results:We ended up with 15 articles,including 7 RCT studies and 8 retrospective cohort studies.A total of 1400 patients,SMP group: 692 cases;RIRS group: 708 cases.SMP and RIRS stone clearance rates were similar [OR: 2.15,95% CI:(1.56,2.98)],and there were differences outside the domestic study.There was no significant difference in SMP and RIRS between the operation time [WMD:-0.40,95% CI:(-8.57,7.77)].SMP was more pronounced than RIRS hemoglobin [WMD: 0.54,95% CI:(0.32,0.75)].There were no significant differences between the two groups in the operation time [WMD: 0.37,95% CI:(0.26,0.48)].There was no significant difference in the incidence of postoperative complications between the two groups [OR: 0.97,95% CI:(0.68,1.36)].Conclusion:SMP versus RIRS can achieve comparable or higher SFR,relatively shorter operative time,similar postoperative hospital stay,slightly higher bleeding,and similar postoperative complication rates.Both SMP and RIRS are safe and effective surgical methods for the treatment of small and medium-sized kidney stones.In clinical practice,reasonable treatment should be selected according to the patient’s condition and willingness. |
