Ex Vivo treatment of stones in living donor kidney by flexible ureteroscopy: Time challenge (case report)

The discovery of a kidney stone in a living kidney donor is rare. The managing technique of this situation and the timing of the treatment of the stone is not well codified.Should it be treated before the removal of the kidney or in ex-vivo after nephrectomy and in cold ischemia ?We report a case of a 60-year-old mom who donates kidney willingly to her son. The decision of the transplant team was for the removal of the left kidney (upper calyx stone of 9 mm) and the treatment of the stone in ex-vivo by flexible ureteroscopy.
