A Scottish woman walked around with a five-inch sex toy inside her for 10 years without realising, doctors have reported. 

The 38-year-old woman arrived at hospital complaining of severe weight loss, shaking and lethargy. 

She had also experienced mild incontinence for 'a few weeks'.

On further examination, doctors were shocked to discover a strange foreign body protruding into her bladder from her vagina, The Daily Mail reports.

Surgical removal of the item at Aberdeen Royal Infirmary revealed it to be a five inch (11cm)-long sex toy.

Medical staff were even more taken back when the woman revealed she had used the sex toy with her partner ten years ago. 

She also admitted she was under the influence of alcohol at the time - and claimed she couldn't remember removing it or not. 

The woman had a normal IQ, no signs of depression or psychosis and had not been subject to any abuse, according to the case report.

But the sex toy had caused her potentially life-threatening damage. 

The woman was suffering from a rare 'vesicovaginal ?stula' – an abnormal tract which allows urine to flow into the vagina. 

The patient’s case - reported in The Journal of Sexual Medicine - is the first time a sex toy has been left inside a woman for as long as a decade.
