Abstract
Spontaneous perforation of the uterus and intravesical intrauterine device (IUD) is very rare. The treatment options for an intravesical IUD are open surgery or cystoscopic removal. Open surgery has been used generally for the removal of IUDs with formation of big stones or partial penetration of the bladder wall. In this case, we removed an IUD (multiload Cu 375) with calculus that had sunk deeply into the bladder wall via laparoscopic partial cystectomy.
