Abstract:
Percutaneous radiofrequency ablation is a common procedure to treat atrial fibrillation. We describe a patient without a urologic history who had immediate abdominal pain after this treatment. Computed tomography scan and cystoscopy/retrograde pyelography confirmed a right proximal ureteral injury with urinary extravasation. The patient was treated with right ureteral stent placement and urethral catheter drainage. This case appears to be the first report of percutaneous radiofrequency ablation complicated by spontaneous ureteral injury related to blunt injury during manipulation of the transseptal sheaths or intracardiac catheters.
