Physicians examining a Scottish woman were surprised (as was she) to discover that a five-inch sex toy had been inside her vagina for a decade.
From News.com.au:
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.
