MARTINEZ, Calif. (AP) _ A man whose penis was amputated is seeking $800,000 from the county, claiming mistakes at a county hospital led to the operation.

Jesse Sandoval, a diabetic, accuses Contra Costa County of negligence.

Sandoval went to Merrithew Memorial Hospital on Oct. 27 for a sore on his penis, according to a claim filed with the county, just east of San Francisco. The next day, surgeons operated to relieve tightness on the skin.

He returned to the hospital Nov. 3 and surgeons amputated his penis some time after that, the claim said, without specifying a date.

The amputation could have been avoided if doctors had given Sandoval antibiotics and a circumcision when he first went for help, according to the claim.

Sandoval is seeking compensation for the loss of his penis and the amputation's effect on his marriage. Officials at the hospital would not comment.

The county is reviewing the claim, but has not determined whether doctors erred, Deputy County Counsel Gregory Harvey said. He said he probably would recommend that county supervisors reject the claim when they are scheduled to review it May 9.

Sandoval's diabetes could have caused circulatory problems, Harvey said.
