We report a case of ureteral migration of a surgical clip after partial nephrectomy in which the clip was misdiagnosed as a ureteral stone. A 37-year-old woman had undergone laparoscopic partial nephrectomy of right renal cell carcinoma at another hospital 2 years previously. Postoperatively, she had gradually acquired lower urinary tract symptoms. Then, she complained of sudden right flank pain for a week. A plain X-ray and enhanced abdominopelvic computed tomography scan were performed. A 0.5 cm×1.0 cm right upper ureteral opacity with borderline hydronephrosis was seen but could not be found on the X-ray. Ureteroscopy revealed a medium-sized Hem-o-Lok clip on the right upper ureter that was removed with a stone basket. We concluded that a Hem-o-Lok clip used for collecting system sealing had migrated to the ureter and had been misdiagnosed as a ureteral stone on a computed tomography scan.
