Ureteroscopy is a favored treatment due to its higher stone-free rates; however, it encounters difficulties in cases of a high burden of distal ureteral stones. We present a case where a patient with a significant ureteral calculus was effectively treated with a vacuum-assisted mini-percutaneous nephrolithotomy system in retrograde approach. This intervention enabled the complete removal of the stone, leading to the patient's full recovery without complications.MedicineArticleSCOPUS10.1016/j.eucr.2023.1026222-s2.0-85177083952
