Objectives. The study presents a comparative analysis of the mini-percutaneous nephrolithotripsy (mini-PCNL) and retrograde nephrolithotripsy (RIRS) with a logistic analysis of outcomes and complications. Material and methods. The prospective study included 50 patients diagnosed with urolithiasis from 2018 to 2021 in the urological hospitals in Irkutsk. Patients were divided into two groups: RIRS (group I, n = 23) and Mini-PCNL (group II, n = 27). The comparison groups are statistically homogeneous. Results. Both procedures equally lead to high stone free rates (SFR > 1 mm, 91.3% vs 85.1%; p = 0.867; SFR > 2 mm, 95.6% vs 92.5%; p = 0.936). The intergroup analysis of the total operation time (and lithotripsy) demonstrated similar times (p > 0.05). Postoperative complications of classes II-III (Clavien-Dindo) in the early and late postoperative period developed rarely and were comparable (p > 0.05). Class I complications were predominant in the PCNL group (p = 0.007). Some parameters demonstrated the superiority of RIRS over PCNL: less pronounced pain syndrome (p = 0.002), less drainage time (p < 0.001), no postoperative hematuria (p = 0.002), shorter hospitalization and total treatment period (p < 0.001). Conclusions. The study highlighted the positive effect of the one-day surgery principle on the risk of developing postoperative hematuria, urinary infection, or severe postoperative pain. RIRS and mini-PCNL have similar effectiveness, but RIRS meets the criteria of the enhanced recovery program more than PCNL.
