Urinary complications of migrated intrauterine contraceptive device

Abstract

The study aimed to present diagnosis and management of urinary complications resulting from migration of intrauterine contraceptive device (IUD). Between May 2002 and January 2007, eight women were treated for urinary complications because of migrated IUD. Persistent lower urinary tract symptoms were the main complaint in five cases, while one patient presented with urinary incontinence and two had suffered from right loin pain. Diagnosis was established after performing noncontrast computed tomography (NCCT) in all cases. Intravenous urogram (IVU) was carried out for evaluation of hydronephrosis in two cases. Cystoscopy was performed before surgical intervention in six cases. The interval between insertion of IUD and onset of symptoms ranged from 1 week up to 2 years. NCCT revealed complete intravesical position of the IUD with calculus formation on top in four cases and partial bladder wall penetration in the fifth. Cystoscopy confirmed the site of the IUD as detected by NCCT. In the last two cases, retroperitoneal migration of IUD had led to fibrosis around the right pelvic ureter. Intravesical IUDs and stones were successfully retrieved using transurethral endoscopy while suprapubic retrieval of the device was followed by repair of vesicouterine fistula in the fifth case and ureteroneocystostomy in the last two cases. Persistent lower urinary tract symptoms in women with IUD should raise the suspicion of intravesical migration. Noncontrast CT permitted excellent depiction of the site of migrated IUD for selection of proper management. Endoscopic retrieval is feasible and safe in cases with intravesical migrated IUD.
