Is RIRS emerging as the preferred option for the management of 2 cm-4 cm renal stones: our experience.

Introduction: The European Association of Urology (EAU) and the American Urological Association (AUA) guidelines recommend percutaneous nephrolithotomy (PCNL) as the first-line treatment of renal stones greater than 20 mm, however multistage retrograde intrarenal stone surgery (RIRS) is reported to have high stone-free rates (SFR), fewer complications and a rapid learning curve. This study presents our experience of RIRS in the management of 2 cm-4 cm renal stones.

Materials And Methods: A retrospective study was performed of all patients who underwent RIRS for 2 cm-4 cm renal stones over a period of 22 months.
