All included patients had complete perioperative data and postoperative non\u2010contrast CT imaging at 4\u20136\u00a0weeks. Of these, 95 underwent BSS\u2010RIRS and 107 underwent unilateral RIRS. Demographic, clinical and operative variables were analysed. Stone\u2010free status (defined as residual fragments \u22644\u00a0mm) and complication rates (within 30\u2009days) were assessed.\n                      <jats:bold>Multivariable logistic regression<\/jats:bold>\n                      was used to adjust for potential confounders.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>BSS\u2010RIRS patients had significantly longer operative times compared to the unilateral group (106.9 vs. 87.3\u2009minutes, p\u2009&lt;\u20090.001) and were more likely to be treated with thulium lasers (73.4% vs. 54.2%, p\u2009=\u20090.003). Preoperative stenting was notably less common in the BSS\u2010RIRS group (39% vs. 65.4%, p\u2009&lt;\u20090.001). Despite these differences, early complication rates remained low and statistically similar between groups (2.1% vs. 3.7%, p\u2009=\u20090.49), with adjusted regression analysis showing a possible non\u2010inferior BSS\u2010RIRS early complication rate (OR 0.36, p\u2009=\u20090.209). Overall stone\u2010free rates were comparable (85.3% vs. 82.3%, p\u2009=\u20090.56). In regression analysis, bilateral RIRS showed increased odds of stone\u2010free status, but this was not statistically supported (adjusted OR 1.62, 95% CI 0.64\u20134.10, p\u2009=\u20090.309). Grade A stone\u2010free status (0\u00a0mm residual) was significantly lower in the bilateral group (72.8% vs. 93.2%, p\u2009&lt;\u20090.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Ambulatory BSS\u2010RIRS is a safe and effective approach for managing bilateral renal stones, offering comparable overall stone\u2010free rates and complication profiles to unilateral RIRS.
