Perforation is one of the most serious but a rare complication secondary to the insertion of an IUD, while perforation into the intravesical organs such as the bladder is even more rare. A 30-year-old multipara in early 30s, with two previous caesarean sections (CS) and one curettage, was found to have her IUD puncturing the bladder during a cystoscopy procedure to remove her bladder stones. Transvesical migration of an IUD is an uncommon complication with a high rate of calculi formation, which is thought to be caused by the IUD\u2019s lithogenic potential. Imaging approaches such as ultrasound and pelvic X-rays are considered imperative in the accurate diagnosis. Any migrated IUD should be removed regardless of location. Prompt and continual monitoring of women using an IUD is essential and in a case where the IUD has migrated, the removal using the endoscopic approach is a safe and effective method.<\/jats:p>","DOI":"10.1136\/bcr-2023-256547","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T03:26:20Z","timestamp":1698204380000},"page":"e256547","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Intrauterine device migration into the bladder leading to stones formation"],"prefix":"10.1136","volume":"16","author":[{"given":"Akbar Novan Dwi","family":"Saputra","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Universitas Gadjah Mada, Yogyakarta, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5383-7571","authenticated-orcid":false,"given":"Nisa Utami Ika","family":"Permatasari","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Universitas Gadjah Mada, Yogyakarta, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,10,24]]},"reference":[{"key":"2025082722353790000_16.10.e256547.1","first-page":"2091915","article-title":"A mislocated Intrauterine device migrating to the urinary bladder: an uncommon complication leading to stone formation","volume":"2020","author":"Nouioui","year":"2020","journal-title":"Case Rep Urol"},{"key":"2025082722353790000_16.10.e256547.2","doi-asserted-by":"crossref","first-page":"3194","DOI":"10.12998\/wjcc.v10.i10.3194","article-title":"Ectopic intrauterine device in the bladder causing cystolithiasis: a case report","volume":"10","author":"Yu","year":"2022","journal-title":"World J Clin Cases"},{"key":"2025082722353790000_16.10.e256547.3","doi-asserted-by":"crossref","unstructured":"Hosseinkhani A , Tabatabaei F , Mosaffa-Jahromi M , et al .
