Over the last decade, there have been vast advancements in endourology, with innovation lead-ing to large renal stones being successfully treated with minimal to no incisions.As the elderly population is growing, we are seeing a trend of more complicated stone patients who are not suitable candidates for percutaneous nephrolithotomy (PCNL) and would require several attempts with conventional flexible ureteroscopy.We aim to share our experience using the ClearPetra Suction Access Sheath and UROFINO Disposable Ureteroscope to completely fragment a large renal stone in a frail elderly patient in a single sitting.
