35-year-old man has ostrich egg-sized bladder stone removed

A man in the Islamic Republic of Iran who went to a hospital because of discomfort in his bladder was found to have a massive stone about the size of an ostrich egg, and underwent surgery to have it removed, according to The Financial News.
On the 7th, science outlet LiveScience reported that the 35-year-old man, who lives in the Islamic Republic of Iran, received this diagnosis after visiting a urology clinic.
The man reportedly had no particular difficulty urinating and no history of prior surgery or underlying disease. He also showed none of the usual symptoms of a urinary tract infection, such as frequent urination or a burning sensation when urinating.
When doctors palpated his abdomen, they detected a large, smooth, hard mass above the pubic bone. The object was not attached to the pelvis or abdominal wall, and an ultrasound scan showed it to be an egg-shaped mass with a diameter of about 11 cm.
The medical team diagnosed the object as an abnormally large bladder stone. Such stones form when minerals in the urine crystallize, and they are typically composed of about 85% calcium.
After checking whether the stone was obstructing or compressing the urinary tract, the doctors surgically removed it. The extracted stone was enormous, weighing 826 grams and measuring about 13 cm in length, 10 cm in width, and 8 cm in height.
The report noted that cases of giant stones requiring surgical removal are "extremely rare." However, this stone is said to fall short of the world record. In 2003, surgeons in Brazil removed a stone that weighed 1.9 kilograms and measured 17.9 cm in length.
