Unusual migration of intrauterine device into bladder and calculus formation.

Received April 2006 Accepted October 2006 INTRODUCTION Foreign bodies in the bladder can result in recurrent urinary tract infection (UTI), hematuria, calculus formation, and pelvic pain.(1) Instruments used for surgical and endoscopic procedures or masturbation may migrate into the bladder. Intrauterine device (IUD) is a safe and cost-effective means of contraception.(2) However, since its application, many complications including dysmenorrhea, hypermenorrhea, pelvic infections, pregnancy, spontaneous abortion, uterine rupture, and migration into the neighboring organs have been reported.(3,4) Migration of the IUD into the bladder has been rarely reported in the literature. We report a case of IUD migration into the bladder and calculus formation.
