A California surgeon has been disciplined for removing a prisoner's healthy kidney and leaving the diseased one intact.

The Orange County Register reported Tuesday that the state medical board placed Dr. Charles Coonan Streit on probation for three years.

The board said Streit, a urologist who has had his license for 41 years, relied on memory to decide which kidney to remove because he didn't have access to the patient's complete medical records.

The 2012 operation at Fullerton's St. Jude Medical Center involved a 59-year-old federal inmate. The hospital was fined $100,000 because CT scans were left in an office on the day of the surgery.

The inmate underwent a second procedure to have the cancerous kidney removed.

An attorney representing Streit didn't reply to a message seeking comment.
