Kidney stone

The existence of kidney stones was first recorded thousands of years ago, and lithotomy for the removal of stones is one of the earliest known surgical procedures. Ammonius, who practiced lithotomy in Alexandria in around 200 BC, acquired the surname Lithotomus from the instrument he developed for fragmenting stones too large to pass through a small perineal incision.

Dornier MedTech introduced in 1980. extracorporeal shock wave lithotripsy for breaking up stones via acoustical pulses, and this technique has since come into widespread use.

For years, the Guinness World record for the heaviest kidney stone was one that weighed 620 grams - the same as four billiard balls. It was successfully removed by doctors in Pakistan from Wazir Muhammad on June 24, 2008.

The record stood until June 1, 2023, when a Sri Lankan man named Canistus Coonghe had a kidney stone removed that weighed 800 grams (1.76 pounds). The stone was 13.372 centimeters (5.264 inches) long and 10.55 centimeters (4.15 inches) wide. It was the largest and heaviest kidney stone ever removed.

Coonghe's kidney stone was so large that it caused him severe pain and difficulty urinating. He was eventually admitted to the Colombo Army Hospital, where doctors performed surgery to remove the stone. The surgery was successful, and Coonghe is now recovering well.
