Primary hyperoxaluria: Long-term outcomes of isolated kidney versus simultaneous liver/kidney transplant.

Objectives: To compare long-term transplant outcomes (organ rejection and retransplant) of simultaneous liver/kidney transplant (SLK) versus isolated kidney transplant (IK) for patients with primary hyperoxaluria (PH).

Methods: The Rare Kidney Stone Consortium PH registry was queried to identify patients with PH who underwent SLK or IK from 1999 to 2021. Patient characteristics and long-term transplant outcomes were abstracted and analyzed.
