Heterotopic ossification of percutaneous nephrostomy tract.
Heterotopic ossification is a rare, abnormal formation of true bone within extraskeletal soft tissues and is a common complication after musculoskeletal trauma or orthopedic procedures. We report a case of heterotopic ossification of a percutaneous nephrostomy tract causing flank pain and masquerading as a retained nephrostomy catheter in a young steroid-dependent man with sarcoidosis 2 years after percutaneous nephrolithotomy. The patient's underlying sarcoidosis combined with local tissue ischemia likely contributed to this rare complication.
