    Abstract:
    AIM: An IUD perforating the uterus and bladder and creating a nidus for stone formation is a rare complication. We aim to demonstrate with a video a novel surgical technique that involves transcervically extracting a perforating IUD with a transurethral nephroscope after removal of the bladder stone on the IUD. METHODS: A 57-year-old woman was referred to our department 4 months ago following a 2-year history of suprapubic pain at the end of urination. Ultrasound and X-ray examination confirmed an IUD perforating the uterus and the bladder. The patient underwent transurethral holmium laser lithotripsy and transcervical removal of the IUD with the aid of a transurethral nephroscope. RESULTS: The stone on the perforating ectopic IUD was successfully removed and the IUD was extracted without complications. CONCLUSION: This video demonstrates a rare case of an IUD that perforated both the bladder and the uterine walls and created a nidus for stone formation in the bladder. The surgical technique involved in removing the stone and extracting the IUD is a new approach to treating this problem. It is suspected that this specific surgical intervention may also help to minimize the formation of a larger vesico-uterine fistula by decreasing the extent of trauma potentially created when extracting the IUD. However, this supposition merits further study.
