Percutaneous Nephrolithotomy versus Retrograde Intrarenal Surgery for Lower Pole Renal Stones in Geriatric Patients: A Comparative Study
This comparative study of 133 geriatric patients with isolated lower pole renal stones found that while PCNL involves greater perioperative morbidity than RIRS, both procedures yield comparable stone-free rates, suggesting that treatment selection should be guided by stone burden and overall patient risk rather than clearance expectations alone.
