Renal transplantation and urinary lithiasis

Renal lithiasis in renal donors is rare. A renal stone in a donor, or in a renal transplant, is not a contraindication for harvesting nor transplantation. If possible, the stone must be removed at the time of the transplantation. The risk of lithiasis is increased in the renal transplant recipient, with a frequency of 2-6%. Metabolic abnormalities for lithiasis are frequent and can be induced by the immunosuppressive treatment, anticalcineurins. Lithiasis can have a poor prognosis in the renal recipient with a risk for infection or renal dysfunction. Small (< 4-5 mm) stones in a renal. transplant can be followed-up. Stones of 0.5-1.5 cm need an extracorporeal. lithotripsy with a previous safety JJ stent. Stones greater than 1.5 cm can be treated by ureteroscopy or percutaneous surgery.
