Post-surgical Deterioration of Renal Function in Primary Hyperoxaluria

摘要

Primary hyperoxaluria leading to calcium oxalate urinary stones and renal deposits occurs rarely in adults. We report three cases in whom end-stage renal failure was precipitated by urological surgery. In contrast, in one case renal stones were destroyed by extracorporeal shock-wave lithotripsy and renal function was not significantly altered. This emphasises the need for early diagnosis. This may not be easy in adult patients: urolithiasis may not be severe, radiological nephrocalcinosis may be lacking, and renal failure may develop late in life.
