Successful preservation of functional right kidney with giant stones: A rare Chinese case report with literature review.

Renal calculi weighing over 200 g are relative rare in modern urological practice since most stones might cause renal dysfunction before reaching such size. We here reported an extremely rare case of giant stones in single kidney of a 72-year-old Chinese male patient who had 30 years long-term history of lithiasis in the right kidney. These huge kidney stones, total weight 832.6 g were successfully removed with multiple sessions of surgery. Kidney function was relatively stable after long-term medical care in primary care centers. Timely treatment of kidney stones early should arouse more attention worldwide.
