OBJECTIVES: We present our experience
in single-stage bilateral retrograde intrarenal surgery
(RIRS), analyzing the stone free rate (SFR), surgical time,
hospital stay, pre- and post procedure creatinine, stone
composition and complications.
METHODS: Between April 2012 and February
2016, 24 RIRS were carried out in 12 patients with
bilateral renal stones. Patients were 9 men and 3 women
with a median age of 47.5 (range: 55), IMC:
23.59 (range: 12.5).
RESULTS: Mean number of stones per renal unit was 2.7
(range: 12), mostly located in the renal pelvis (40%),
with an average size of 16.08±8.06 mm and an average
stone burden of 258.54±242.59 mm2. The SFR
at 3 months was 83.33%. Average operation time was
75 minutes and median hospital stay was 2 days. Three complications were recorded (25%), all of them minor
(Clavien I-II). No major complications were recorded
CONCLUSIONS: Single-stage bilateral RIRS is a safe
and effective tool for the treatment of patients with bilateral
