:Description

• Objective
  
  To evaluate the long-term stone free rate (SFR) of retrograde intra-renal surgery (RIRS) in the treatment of lower pole renal calculi using only basket relocation and identify independent predictors of stone-free status.
  All consecutive patients treated with RIRS lower pole renal calculi in a single high-volume tertiary center.
• Methods
  All consecutive patients underwent RIRS lower pole renal calculi at a single high-volume tertiary center were analyzed retrospectively. Lower pole stones were relocated to the upper pole, where laser lithotripsy was performed. All patients were followed up in the clinic following the surgery and yearly thereafter. The stone-free status was assessed with a combination of an abdominal ultrasound and abdominal X-ray (KUB), or an abdominal non-contrast computed tomography (NCCT) if the stones were known to be radiolucent.
• Results
  A total of 480 consecutive patients who …
