Flexible Mini Percutaneous Nephrolithotomy Vs Retrograde Intra-renal Surgery

The use of flexible ureteroscopy and minimally-invasive percutaneous techniques, which utilize smaller tract sizes, has been established as a way to decrease the invasiveness of procedures and improve patient outcomes compared to conventional percutaneous nephrolithotomy (PCNL) and flexible mini-PCNL has emerged as a novel technique previously first as an auxiliary procedure and then as a standalone technique. This study aims to assess the feasibility and effectiveness of flexible nephoscopy in improving stone clearance compared to standard retrograde intrarenal surgery using a flexible ureteroscope.
