In the operation not all of the cancer could be removed and a CT scan showed evidence of disease progression and masses in the middle section of her chest cavity. She later had radiotherapy and chemotherapy but she died.
Mr Hill says it was unsatisfactory that the woman and her daughter-in-law were left with the impression at the meeting with the registrar in August 2012 that the woman would be fine following surgery.
The commissioner's office says he recommended the DHB report to him about changes made since the complaint, including:
• A new surgical booking form,
• A tracking and audit system,
• The appointment of a nurse coordinator in the urology department, and
• The progress of its recruitment strategy to appoint another urology consultant.
DHB chief medical officer Dr Geoff Robinson issued a statement tonight about the findings.
"On behalf of the DHB I want to pass on my condolences to the family and apologise for the delays in the care we provided," he said.
"We accept the HDC's findings and have made changes to our services to ensure the situation that led to the delayed surgery in 2012 does not occur again."
Dr Robinson said advance care planning discussions between patients, their families and clinicians is a priority for the DHB.
"We continually promote the importance of advance care planning to our staff and provide them with resources and skills."
