Kidney stone size of a coconut removed

A coconut-sized kidney stone 6in in diameter has been removed from a patient in Hungary.
Sandor Sarkadi underwent an abdominal operation in Debrecen, 150 miles east of Budapest, after doctors discovered the stone following an X-ray.
Mr Sarkadi was rushed into an operation in the Kenez Gyula Hospital after the X-ray showed a giant lump.
Kidney stones do not normally get much bigger than a golf ball, and even that is usually considered very large.
After a kidney stone forms, it will often pass through the urinary system, but it is fairly common for a stone to block the urinary system. "OUCH"
