A 85-year-old man near Da Lat is recovering after doctors removed a 900 grams stone from his bladder.
Doctor Nguyen Xuan Vinh, director of the Hoan My Da Lat Hospital, told Tuoi Tre newspaper on Tuesday that K’ Tieng has been recovering well.
The ethnic man from a rural district in Lam Dong Province was hospitalized on Tuesday morning as he was weak and had difficulty urinating, the paper said.
X-ray and ultrasound scan photos showed he had a bladder stone.
Doctors at the hospital spent an hour performing a surgery to remove the stone, which measured 10 centimeters in length and seven centimeters at the widest part.
Vinh said such a large bladder stone is rare.
He said bladder stones are usually the size of a finger tip and can be got rid off without a surgery.
Doctors recommend that people who have urination problems, who urinate blood or opaque urine should receive an abdomen ultrasound scan to detect stones.
