“…Apart from types of foreign bodies reported in this study (needle, bullet, electric wire, IUCD), a variety of other objects have been reported to migrate into the urinary bladder from the surrounding pelvic organs, including vaginal pessary, artificial urinary sphincter, prosthetic slings and TVT tapes, nonabsorbable sutures and tacks used in Stamey procedures and Burch colposuspension, surgical gauze and orthopaedic screws and wires [1,2,[4][5][6]. Even a major group of self-inflicted foreign bodies which were actually inserted in distal and bulbar urethra, further migrate into bladder by involuntary prerineal muscle contaction and could not be retrieved by the patient itself.…”
