Miniaturized percutaneous nephrolithotomy (mini-PCNL) reduces morbidity, but concerns remain about stone-free rates (SFRs) and infection. Suction-assisted mini-PCNL (SM-PCNL) enhances fragment removal and controls intrarenal pressure, but its role in anomalous kidneys is unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>To evaluate perioperative outcomes of SM-PCNL in anomalous kidneys in a multicenter, real-world study and assess variations based on positioning, lithotripsy modality, and renal anomalies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methodology:<\/jats:title>\n                    <jats:p>This prospective study across 15 centers (January\u2013December 2024) included 287 adults undergoing SM-PCNL for renal stones in anomalous kidneys.
