A Medical Council's fitness to practise inquiry has found anaesthetist Dr Hossam Desoky guilty of two counts of professional misconduct and two counts of poor professional performance.
The inquiry found against him for inviting patient Teri Chamberlain to his on-call residence room and kissing her. It ruled this amounted to professional misconduct.
It also ruled that it was also poor professional performance for him to call Ms Chamberlain on her mobile phone and not keep adequate medical records of a chest examination.
Six other allegations were not upheld.
A report on the inquiry will now go to the full Medical Council.
It will then decide on what sanction should apply to Dr Desoky.
Ms Chamberlain said she was pleased with the outcome of the inquiry, but disappointed with some of the verdicts.
She said she felt very let down by South Tipperary General Hospital.
