Surgery and Discovery
In Trincomalee, a city on Sri Lanka's eastern coast, surgeons extracted a bladder stone weighing 3.1 kilograms (6.8 pounds) from a 55-year-old man. The procedure took place last week at a local hospital. The patient had been admitted after suffering a stroke, and during his treatment, doctors noticed he was having trouble urinating, which led them to discover stones in his bladder.[S1]
A 3.1kg stone, comparable in size to an ostrich egg and weighing as much as a newborn baby, was extracted from a man's bladder by surgeons. Dr. Prahalahan Balakrishnan, the lead surgeon, informed BBC Sinhala that this is the largest bladder stone ever recorded and surgically removed, based on available documentation. Remarkably, the patient was in excellent health, according to Dr. Balakrishnan.[S1]
Patient's Condition and Stone Formation
The patient is still in the hospital, receiving ongoing care for various health issues. Dr. Balakrishnan's assessment indicated that the bladder stone had been growing for approximately five to ten years. These stones occur when urine minerals solidify into crystals, often due to incomplete bladder emptying, which leads to concentrated urine that can crystallize.[S1]
Bladder stones can vary in size, from tiny grains of sand that pass naturally to massive growths that cause serious health issues. Stones over one centimeter can obstruct urine flow, necessitating medical treatment. A stone exceeding four centimeters is considered exceptionally large. In a remarkable case in Sri Lanka, doctors removed a bladder stone measuring an astonishing 17 centimeters in length.[S1]
Record Comparison
The previous record for the largest bladder stone, as recognized by Guinness World Records, belonged to a Brazilian patient in 2003. This stone was a substantial 1.9 kilograms (4.2 pounds) in weight and measured 17.9 centimeters (7 inches) in length. However, the recent discovery in Sri Lanka surpasses this, weighing an impressive 3.1 kilograms, potentially earning it the title of the largest documented bladder stone.[S1]
