Question in relation to uteral infection cause by a lodged tampon?

A friend has have a tampon or a piece of a tampon lodged in her uterus for the ending 18 months and she can't find a doctor who will listen to her, because they all ponder it's something else. She now have a bad infection and is too sick to work. Anyone have any experience with her situation? it is humanly impossible for a piece of tamponto draw from lost,it cant possibly get into the uterus,as the cervix is closed,and the vagina is one and only 1to 2 inches long and can be seen rather easily beside a speculum
she needs to budge to a gynecologist who will look in in that for her.
