Prince Charles' wife Camilla, the Duchess of Cornwall, underwent a hysterectomy at a London hospital Monday, officials said.

Camilla, 59, arrived for the procedure at the King Edward VII hospital on Sunday, having recently returned to Britain following a 10-day tour of the Mideast with Charles.

"The Duchess of Cornwall had her operation this morning and is recovering well," Prince Charles' office said in a statement.

Officials said Camilla is expected to remain in the hospital for the rest of the week.

A hysterectomy is a surgical procedure to remove all or part of the uterus. The operation can be done for various reasons, including cancer, abnormal growths, menstrual problems or complications following birth.

Clarence House had said the operation was not the result of cancer, but did not provide any further details.

Camilla is expected to require six weeks of recuperation.
