Surgeons in Sri Lanka have removed the largest and heaviest kidney stone ever recorded.This was confirmed by Guinness World Record on Thursday.
The colossal kidney stone was removed from a 62-year-old retired soldier Canistus Coonghe (Sri Lanka).Measuring 13.37 cm (5.26 in) in length and 10.55 cm (4.15 in) in width, which is the world’s largest kidney stone ever recorded.
The stone was in fact larger than Coonghe’s actual kidney, which has a bipolar length of 11.8cm (4.6 in).The previous record had not been surpassed since 2004, when a 13 cm (5.11 in) kidney stone was surgically removed from an Indian man named Vilas Ghuge. 
Coonghe’s kidney stone is also the world’s heaviest kidney stone, weighing 800 g (1.76 lb) roughly having the same weight as five baseballs.The previous record was 620 g (1.36 lb), set by Wazir Muhammad (Pakistan) in 2008.Coonghe’s record-breaking kidney stone was in his right kidney and was identified by the urological team at Army Hospital, Colombo, Sri Lanka.
Coonghe underwent a procedure called open pyelolithotomy, whereby the stone was surgically removed through an incision made in the pelvis of his kidney. The operation was performed by Dr Kugadas Sutharshan on 1 June.Fortunately, despite the blockage, Coonghe’s kidney was still functioning normally, according to the doctors.His liver, gallbladder, pancreas and spleen were described by Dr Sutharshan as “normal” in size, although Coonghe’s prostate was enlarged.
