A 36-year-old woman underwent a successful renal transplantation after loss of renal function from hyperoxaluria. At 24 months post-transplantation she still has excellent renal function. The success of this procedure is attributed in part to the use of pyridoxine hydrochloride, which has somewhat reduced oxalate excretion, and methylene blue, which apparently has prevented the crystallization of oxalate in the urine despite high excretion rates.
