Migration of intrauterine devices (IUDs) to the ureter causing ureteral obstruction is an extremely rare event. A 45-year-old female patient was admitted to our hospital with a complaint of pain in the right flank and inferior right quadrant of the abdomen. On genitourinary system ultrasonography, grade 3 hydronephrosis was found in the right kidney. On the abdominopelvic radiography, there was an appearance consistent with two IUDs, one in the region consistent with the course of the right distal ureter and the other in the usual localisation. The first IUD was thought to have spontaneously detached from the uterus, so a second IUD was implanted. A right-sided extravesical ureteroneocystostomy (Lich-Gregoir) operation was performed. The operation was terminated with the placement of a 4.8 French, 26 cm double-J stent in the ureter. The patient was followed up in our hospital for 26 months and she was asymptomatic during follow-up, hydronephrosis was resolved completely, and no complications were encountered during follow-up clinical and ultrasonography examinations.
