Migration of left hip pin with involvement of left ureter.

This patient had hematuria and a history of hip fusion many years before. It was found that a left hip pin had broken, and its sharpened portion had migrated through the head of the femur into the adventitia of the left ureter. During exploratory surgery, a bonecutter was employed to cut off the tip of the pin flush with the pelvic wall. The patient has had no recurrence of hematuria. Review of the literature disclosed no report of a similar case.
