Super‐mini percutaneous nephrolithotomy ( <scp>SMP</scp> ) vs retrograde intrarenal surgery for the treatment of 1–2 cm lower‐pole renal calculi: an international multicentre randomised controlled trial

Abstract

SMP was more effective than RIRS for treating 1-2 cm LPC in terms of a better SFR and lesser auxiliary procedure rate. The complications and hospital stay were comparable. RIRS has the advantage of less postoperative pain.
