A non-contrast helical CT was performed at 3 months postoperatively to detect residual stones accurately. Patients’ clinical characteristics, stone demographics, and perioperative outcomes were collected and statistically analyzed RESULTS: After PSM, 60 patients from the F-URS cohort were matched to 60 similar patients from the Mini-PCNL group. The results of clinical characteristics and postoperative outcomes following PSM are listed in Table 1. The stone-free rate (SFR) after PSM was not significantly higher in the Mini-PCNL group than the F-URS group (91.7% vs. 81.7%, respectively p=0.1). The median operative time for the F-URS group was significantly shorter than the Mini-PCNL group 54(49-64.3) and 68.2(62-73.5), respectively p=0.045 Table 1. CONCLUSIONS: Ambulatory Mini-PCNL and F-URS have a comparable hospital stay, SFR, and complication rates for treating lower calyceal stones 10-20mm. Both techniques may be considered acceptable treatment options, with a prolonged operative time in Mini-PCNL.
