Complete perforated bladder from intrauterine devices: A case series report from a nationwide monitoring system

Abstract

AbstractAimComplete perforation of the bladder caused by an intrauterine device (IUD) is rare. This study examined the characteristics of patients associated with IUD‐related bladder perforation and evaluated the relationship between mislocated IUDs and their potential complications.MethodsFrom October 2005 to December 2021, 13 reports regarding complete perforations to the bladder by IUDs were retrieved from the National Contraceptives Adverse Reaction Monitoring System of China. The clinical features of these cases were analyzed.ResultsThe median patient age was 30 (range, 27–46) years. There were four cases (4/13, 30.8%) with IUDs placed during lactation, one case (1/13, 7.7%) with an IUD placed after medical abortion, and eight cases (8/13, 61.5%) placed after menstruation. Seven cases (7/13, 53.9%) were first‐time IUD users. The median duration of IUD placement was 47 (range, 1–145) months. Unexpected pregnancy was reported in five cases (5/13, 38.5%). Six cases (6/13, 46.2%) reported bladder stones with varying degrees of abdominal pain or urinary tract infection. Removal methods included laparotomy (four cases), cystoscopy (four cases), laparoscopy (two cases), laparoscopy combined with cystoscopy (two cases), and laparotomy after cystoscopy (one case). All IUDs were successfully removed.ConclusionsComplete perforation to the bladder by IUDs is a rare adverse event. Regular follow‐up is required after the placement of IUDs. The possibility of uterine perforation should be investigated if IUD users encounter persistent lower abdominal pain or urinary tract infection.
