Hydronephrosis due to a Migrated Intrauterine Device into the Ureter: A Very Rare Case.

Intrauterine device (IUD) insertion is a long-acting and one of the most effective modes of reversible contraception. Complications that most commonly arise following IUD insertion are failed insertion, pain, vasovagal reactions, infection, menstrual abnormalities, and expulsion. In this paper, we present the case of a woman who experienced hydronephrosis due to the migration of IUD into the ureter after 30 years of insertion. To the best of our knowledge, this is the third such case reported in the literature.
