The complications of percutaneous nephrolithotomy (PNL) include hemorrhage, damage to adjuvant organs, and other medical issues, although intracardiac migration of ureteral double-J stent has never been found during PNL and delaying the diagnosis might cause mortality. We report the case of a 60-year-old male who was admitted to receive one-stage PNL for right renal stones. During operation, an unexpected atrial fibrillation with a drop in blood pressure was suddenly encountered and the chest X-ray subsequently showed that the ureteral double-J had penetrated deep into the heart. Emergent endovascular intervention was performed to remove the stent and the patient was uneventfully discharged 2 days later.
