A man from south-east China reportedly had a padlock stuck in his bladder after inserting it into his penis.
The small lock was said to have travelled down the man’s urethra, the passageway between the bladder and the external part of the body.
In cringeworthy scenes, the victim’s family had even gone to hospital with him in the Chinese city of Fuzhou.
Doctors were able to operate on him and remove the padlock from his bladder.
It is not known if the bizarre incident will leave any lasting damage.
Earlier this year, another man had 15 rusty needles removed from his penis after he inserted them for “excitement”.
Doctor Cao Zhiqiang, who took part in the operation to have the four-inch needles removed, said: “Because of the patient’s… hobby, he inserted 15 needles from the tip of his penis into his urethra over the course of a year.
“Had we waited longer, the needles might have moved further up into his bladder, which would have been very troublesome.”
