Which Patinets Benefit More From Percutaneous Nephrolithotomy? A Location-Based Comparative Analysis of PCNL and RIRS for 1-2 cm Renal Stones

Résumé succinct

This prospective randomized controlled trial aims to compare the clinical efficacy and safety of Percutaneous Nephrolithotomy (PCNL) and Retrograde Intrarenal Surgery (RIRS) for renal stones measuring 10-20 mm. The study specifically investigates whether the anatomical location of the stone (upper, middle, or lower calyx) influences the success rates and stone-free outcomes of these two surgical modalities. A total of 110 patients were randomized into two equal groups to evaluate primary endpoints, including stone-free rates at the 3-month follow-up, and secondary endpoints such as operative time and complication rates
