Safety and Feasibility of Salvage Endoscopic Combined Intrarenal Surgery in Embolized Kidney

Background: Although endoscopic combined intrarenal surgery (ECIRS) is well established as primary approach to complex lithiasis, no evidences are still available on its use in salvage context. Case Presentation: A male patient, of 55 years of age, underwent many unsuccessful surgical procedures to treat large and multiple right kidney stones, including percutaneous nephrolithotomy (PCNL). The latter was complicated by severe postoperative hemorrhage, managed with super-selective renal artery embolization (SRAE). Therefore he came to our institution to achieve a complete resolution of the urolithiasis. Preoperative evaluation included CT scan and renal scintigraphy to establish kidney and stone morphologic features and residual renal function. Salvage ECIRS was performed and postoperative assessment showed a complete resolution of lithiasis and absence of renal function impairment. Conclusion: To our knowledge, this is the first case of salvage ECIRS reported in literature after previous failed PCNL. Even after SRAE, this procedure appears as safe and as efficacious as standard salvage PCNL when performed by experienced hands.
