All five patients with bilateral disease were managed with a staged approach in two separate surgical sessions. RPF was idiopathic in 37% and secondary in 62% of cases. Four procedures (19%) were aborted due to extensive fibrosis or high vascular risk (one unilateral right, two unilateral left and one second\u2010stage left unit). These patients had significantly longer preoperative stent duration (60 vs. 9\u00a0months;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006). Among the 17 completed procedures, no open conversions, intraoperative complications or transfusions occurred. Median operative time was 215\u2009min (IQR 195\u2013240), and median blood loss was 10\u00a0ml (IQR 10\u201320). Median length of stay was 11.5\u00a0h (IQR 7.8\u201326), with 52% of patients discharged the same day. At a median follow\u2010up of 25\u2009months (IQR 18\u201350), complete symptom resolution was achieved in 82% of renal units, whereas 64% remained stent\u2010free at 12\u2009months. The main limitations are the small sample size, single\u2010surgeon experience and absence of a comparator arm.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SP\u2010RAU is a safe and feasible minimally invasive option for managing RPF. It achieves good functional success with minimal morbidity and enables same\u2010day discharge in over half of patients. Larger multicentre studies with longer follow\u2010up are needed to confirm these findings and establish the role of SP\u2010RAU in the management of RPF.<\/jats:p>\n
