Early dysfunction of transplanted kidney revealed the cause of recurrent nephrolithiasis: a case report of primary hyperoxaluria

Primary hyperoxaluria (PH) disorder causes end-stage renal disease (ESRD). Missed diagnosis or relapse in transplanted kidney is common. We present a 36-year-old patient with a history of recurrent renal calculus which progressed to end-stage renal disease. He underwent kidney-transplant surgery. Renal function tests had worsening progressively at first-week post-transplant. Transplanted kidney biopsy lead to the underlying PH. His several admissions and complications make us to report the case and suggest re-evaluation of PH before the kidney transplant in ESRD.
