Bladder urethra foreign body

There are fewer foreign bodies in the upper urinary tract and more common in the lower urinary tract. Lower urinary tract foreign body can be divided into bladder foreign body and urethral foreign body. It is usually caused by gunshot wounds and other penetrating wounds. It can also be caused by human factors, such as non-absorbable sutures left after surgery, electric wires inserted from the urethral orifice, plastic wires, ballpoint pen cores, hair clips, etc. . The foreign body can stay in the bladder for a long or short time, up to several years, and often secondary infections and bladder stones.
