Inclusion criteria encompassed all consenting patients with renal stones managed via prone\/supine SM-PCNL (14\u201322 Fr suction sheath). The digital disposable scope served initially as a cystoscope to place the guidewire and later used for nephroscopy. Data collected included patient\/stone characteristics, operative details (lithotripsy time, access technique), complications (Clavien-Dindo), surgeon satisfaction (5-point Likert scale), and stone-free rate (SFR). SFR was assessed via low-dose CT at 30 days (Grade A: no fragments; Grade B: \u22644\u00a0mm fragment).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Median stone diameter was 1.7\u00a0cm (IQR 1.3\u20132.3). Median lithotripsy and total operative times were 8\u00a0min (IQR 5\u201316) and 22\u00a0min (IQR 20\u201335), respectively. Intraoperative SFR was 96%. Surgeons reported excellent instrument satisfaction (median Likert score 1\/5) for vision, ease of use, and manoeuvrability within the pelvicalyceal system. Complications were rare: major (Clavien\u2009\u2265\u20093) occurred in 0.9% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20093, including colonic injury, pleural injury, sepsis.
