5. I read with interest the letter about uterine perforation with an intrauterine device (IUD) by Vural and colleagues in the July issue of the Journal.1 The authors state that they believe their case to be the first report of bladder perforation by an IUD. However, they cite a paper that gives details of six such cases reported during the 1970s!2 This classic review by;Zakin et al. analyses; cases of perforation at multiple sites and goes on to propose mechanisms by which perforation occurs. Perforation of the uterus and through to the bladder or ureter is an uncommon but regularly reported complication of intrauterine device insertion
