Hidden in <scp>CAKUT</scp>: Post‐Transplant Diagnosis of Primary Hyperoxaluria Type 1 and Rescue Management Using Lumasiran

This case underscores the importance of maintaining a high index of suspicion for PH1 in patients with congenital anomalies of the kidney and urinary tract (CAKUT) or unexplained end-stage kidney disease (ESKD) cases, even post-transplantation. It also demonstrates the potential efficacy of lumasiran in managing PH1 post-transplantation when combined with intensive hemodialysis and supportive care. However, more studies with prolonged follow-up periods are necessary to establish the long-term efficacy and safety of lumasiran in the treatment of PH1 without the requirement for liver transplantation.
