When a man in California went to the hospital because of bladder problems, doctors found a large reason for his pain: a mineral stone nearly the size of an ostrich egg, according to a new report of the case.


The 64-year-old man went to the emergency room because he had pain in his left side and trouble urinating. His doctors found an egg-shaped bladder stone that weighed a whopping 1.7 lbs. (770 grams) and measured 4.7 inches by 3.7 inches by 3 inches (12 by 9.5 by 7.5 centimeters), according to the report. (For reference, a typical
ostrich egg weighs about 3 lbs., or 1,360 grams.)


Bladder stones are mineral masses that form in the bladder.


In some cases, the stones are too small to be seen with the naked eye, but in others, the stones can be quite large, reaching an inch or more in diameter. According to Guinness World Records , the largest bladder stone was 7 inches long, 5 inches thick and 3.7 inches tall (17.9 by 12.7 by 9.5 cm), and weighed 4.2 lbs. (1.9 kg).


CT scans of the man's adbomen also revealed another, much smaller stone in the man's left ureter, which is the tube that carries urine from the kidneys to the bladder, according to the report, which was published today (Sept. 6) in The New England Journal of Medicine .
