World Record...

Some of us are less fortunate than others.

As of April 16, 2003, Dan Winfield of Ontario had produced and passed over 4,504 kidney stones! Some were as small as grains of sand, others were as large as green peas.
Within a 24 hour period, Mr. Winfield made 22 stones. This apparently was when the problem was at its worst. Similarly, in 5 days he produced 35 kidney stones. The former social worker started producing stones in February of 1986, and his condition is well documented with the Mayo Health Clinic in Minnesota. His neighborhood friends in Canada ran a fundraising campaign in October of 1990 so he could get the best medical care.
He had to be placed on a portable morphine pump to reduce the pain. To further reduce the pain, surgeons moved Winfield's kidney down the abdomen, shortening the ureter's length. Unfortunately, that kidney failed and had to be removed. All the while, the right kidney had begun to produce stones.
