All patients had prior systemic UTI management with a minimum 6\u2010week interval before definitive stone treatment.

Forty\u2010seven patients (32.6%) had emphysematous pyelonephritis at initial presentation. Median operative time was 40\u2009min with a 1\u2010day hospital stay. Notable findings included zero cases of sepsis and a 29.9% rate of postoperative fever requiring extended antibiotics up to 2\u00a0weeks. Zero residual fragments were achieved in 48.6% and a single fragment up to 2\u00a0mm in 43.8% of patients (92.4% combined stone\u2010free rate). Renal function improved at 30\u2009days (median creatinine decrease \u221215\u2009\u03bcmol\/L) and 3\u00a0months (\u221218\u2009\u03bcmol\/L).
