An unusual cause of vesical stone: a migrant intrauterine device

Migration of a fractured ring IUD resulting in vesicovaginal fistula and vaginal calculus

CASE

Although many complications have been reported with intrauterine contraceptive devices (IUDs), vesicovaginal fistula with secondary vaginal stones is rare. We report the case of a 46-year-old woman who presented with a vaginal discharge lasting 2 months. Two years previously, she had undergone cystoscopic lithotripsy and surgery to remove an IUD, after pelvic radiography had revealed a fractured Chinese stainless steel ring IUD with secondary vesical stones that had been the cause of her urinary tract symptoms. When she again complained of vaginal discharge, vaginal stones and a vesicovaginal fistula were found on physical examination and CT urography. The patient underwent stone removal and concurrent vesicovaginal fistula repair. IUD fragments were found in the vesicovaginal and rectovaginal spaces. No abnormalities were found at follow-up 6 months after surgery.

CONCLUSION

In any woman undergoing surgery to remove a migrated IUD, complete exposure and removal of the IUD are necessary to avoid fracturing of the IUD, secondary breakage and residue.

[Intrauterine device migration to the bladder: four case reports]

The intrauterine device has been commonly used in our population for many years as contraceptive method. One of the complications is the device migration out of the uterus. One of the most uncommon fait of this migration is the bladder, with few reports on the literature. In this work, four cases are reported with their clinical presentation, study and treatment.

Vesical calculus formation around a migrated copper-T 380-A

The authors report a case of intravesical migration of an intrauterine contraceptive device (IUD) with secondary stone formation in a 28-year-old woman who presented with recurrent urinary tract infections. After incomplete removal of the migrated copper-T 380-A from the pelvic cavity by laparoscopy, cystoscopy was performed and the arms of the IUD with the calculus formed around them were removed via the cystoscope. Intravesical migration of an IUD should be suspected in any woman with an unretrieved device and with recurrent urinary symptoms.
