However, there is no prospective study to evaluate the outcomes of bilateral same session retrograde intrarenal surgery (RIRS). The aim of this study was to prospectively compare the outcomes of bilateral same session RIRS to unilateral RIRS and to compare the outcomes of first to second operated kidney in bilateral same session RIRS. METHODS: Consecutive symptomatic adult patients with kidney stones up to 20 mm that accepted to be treated by RIRS in our Institution from August 2016 to August 2017 were prospectively studied. Stone free rate was evaluated on POD 90 non-contrast CT for each renal unit. Surgical complications based on Clavien-Dindo classification during the 90 days of follow-up were recorded. Outcomes of bilateral same session RIRS were compared to unilateral RIRS. Outcomes of first operated kidney were compared to second operated kidney in bilateral same session RIRS group. RESULTS: Failure in ureteral access sheath placement occurred in 5/74 (6.8%) renal units of planned unilateral RIRS and in 7/54 (13.0%) renal units of planned bilateral RIRS (p=0.234). Sixty-nine patients were evaluated in the unilateral RIRS group and 23 patients with 46 renal units in the bilateral same session RIRS group. Clinical features of unilateral RIRS vs. bilateral RIRS were compared in Table 1. Demographic data and stone characteristics were similar between groups. Outcomes of unilateral RIRS and bilateral same session RIRS were compared in Table 2. Stone free rates were similar between bilateral and unilateral RIRS with less consumption of disposable devices in bilateral group. However, bilateral group had higher complication rate, higher frequency of emergency room visits and higher creatinine during follow-up. First operated kidney outcomes were similar to second operated kidney of bilateral same session RIRS (Table 3). CONCLUSIONS: Although bilateral same session RIRS had similar stone free rate and used less disposable devices compared to unilateral RIRS, we can not recommend as a standard practice because bilateral same session RIRS had higher overall complication rate, higher frequency of emergency room visits and higher creatinine during follow-up. There was no significant outcome difference between first and second operated kidney in bilateral RIRS.
