The mother of a boy who had the wrong kidney removed in a Dublin hospital has said that she asked staff to check the correct operation was planned before her son went into theatre.

The boy is likely to require dialysis for the foreseeable future, or a kidney transplant, following the procedure at Our Lady's Children's Hospital in Crumlin, Dublin, in March 2008.

The Medical Council today began a fitness to practise inquiry into allegations of professional misconduct against the two doctors involved.

The boy, identified only as Master Conroy, was under the care of consultant paediatric surgeon Professor Martin Corbally.

He delegated the surgery to be performed on 21 March 2008 to specialist registrar Sri Paran.

The doctors face allegations that the standard of care fell below what was expected.

The inquiry has been told that the boy's parents were concerned that the wrong kidney had been selected for the surgery.

The boy's mother said she was upset to hear in January 2008 that Master Conroy, who was six at the time, would need an operation.

The woman said her son had medical problems after birth and had a previous operation.

She said the consultant at the Crumlin hospital, Prof Corbally, said her son would require an operation on his right kidney.

Before the operation in March 2008, she raised concerns with a junior doctor and a nurse about the side planned for the operation and asked staff to confirm that the correct operation was to take place before her son went to theatre.

The boy's father told the inquiry that he signed the consent form for the operation.

He said he became frustrated as he could not get a definitive answer as to which side the operation would be performed.

The inquiry was also told that Prof Corbally failed to adequately review radiological imaging in January 2008 and erroneously recorded the left kidney for a nephrectomy.

It is alleged that Mr Paran also failed to adequately review the imaging and did not raise the concerns the parents had with Prof Corbally.

In a statement, Prof Corbally said he incorrectly listed Master Conroy for the removal of the left, rather than the right kidney.

He said he was ultimately responsible for the patient's safety and again unreservedly apologised for the tragic episode.

The inquiry has adjourned until September.
