Nevertheless, in specific instances where an antegrade approach is necessary for lithotripsy, the application of these sheaths is not well established. We present the case of a patient with a neobladder and a significant ureteral calculus who was effectively treated via an antegrade approach using a flexible ureteroscope with a sUAS. This intervention enabled complete stone removal, leading to the patient's full recovery without complications.MedicineArticleSCOPUS10.1016/j.eucr.2025.1031002-s2.0-105008292267
