Sri Lankan Surgeons Extract Record-Breaking 1.3kg Bladder Stone From Patient

A surgical team at the Colombo Army Hospital in Sri Lanka successfully extracted a bladder stone weighing 1.3 kilogrammes from a 62-year-old retired army soldier, according to medical officials. The stone, measuring 13.37cm by 10.16cm, is believed to be the largest and heaviest ever removed from a human, surpassing the 2008 Guinness World Record of a 1.05kg stone found in Brazil.

The patient, whose identity has not been released, is reportedly recovering well following the procedure on 1 June. Dr. Thamasha Premathilaka, a consultant urologist, highlighted the rarity of such a large calculus, noting it was the largest bladder stone he had personally encountered. The medical team published details of the case in the International Journal of Surgery Case Reports.

Bladder stones are solidified masses of minerals that can form in the bladder when urine is concentrated, often due to dehydration or an inability to empty the bladder completely. While smaller stones can pass naturally, larger ones typically require surgical intervention. Untreated, they can lead to infections, blood in the urine, and chronic pain. This extraordinary case underscores the potential for extreme physiological developments when medical conditions are left unaddressed.
