Implication

Randomized trial demonstrates higher stone-free rates with mini-PCNL than flexible ureteroscopy for 1–2 cm lower pole stones, indicating superior clearance with similar complications.

Key Points

To compare the safety and efficacy of ambulatory tubeless mini-percutaneous nephrolithotomy (mini-PCNL) versus flexible ureteroscopy (f-URS) in treating 1–2 cm lower calyceal renal stones.
Randomized controlled trial of 72 patients treated between October 2020 and November 2023 with either mini-PCNL or f-URS.
Computed tomography scans were performed preoperatively, on postoperative Day 1 (POD 1), and at 3 months follow-up to evaluate stone-free status.
All patients underwent ambulatory surgery and were discharged home on the same operative day.
Mini-PCNL achieved significantly higher complete stone clearance (0 cm fragments) compared to f-URS at POD 1 (50% vs 11.1%, P < 0.001) and at 3 months (72.2% vs 37.1%, P = 0.003).
Using a residual threshold of <0.4 cm, mini-PCNL remained superior to f-URS at POD 1 (75% vs 22.2%, P < 0.001) and at 3 months (86.1% vs 65.7%, P = 0.04).
Mini-PCNL required significantly longer median operative time (P = 0.04), while median hospital stay (5 h vs 4 h, P = 0.14) and postoperative complications showed no significant difference.
