Doctors treating a woman for severe weight loss and lethargy were shocked to discover she had a sex toy stuck inside her — and it had been in place for a decade.

According to the Toronto Sun, citing a report in the Journal of Sexual Medicine, the Scottish woman took herself to the hospital complaining that she was tired, incontinent and losing weight.

Upon examination, doctors were surprised to find a 5-inch sex toy protruding into her bladder from her vagina.

The 38-year-old reported using the toy one drunken night with her partner 10 years ago, noting she couldn’t remember whether she had removed it.

Medical staff said the woman suffered a so-called “vesicovaginal fistula,” an abnormal tract that allows urine to flow into the vagina. Urine had also backed up into her kidneys, causing an obstructive uropathy.

Once surgeons removed the toy, doctors were able to repair the damage.

The woman left hospital sex toy-free, and with a dubious new honor: She had held a sex toy inside her vagina for longer than anyone else, the medical journal reported.
