Mary Rose Harkin, from Cranford, underwent unsuccessful breast reduction surgery performed by Dr Towpik at Klinika Latros in July 2009.
The 32-year-old special needs assistant had her case struck out at the High Court in Dublin after a judge ruled that the court had no jurisdiction over the claim.
The operation had been advertised on a UK website and the operation had been carried out in Poland.
Ms Harkin had also signed the consent forms in Poland.
She planned to sue plastic surgeon Edward Towpik, the Warsaw-based cosmetic clinic, Klinika Latros, and its alleged UK based agent, Denise Bird.
She claimed she could do this as an EU citizen and the operation had been carried out in an EU country.
But Mr Justice Nicholas Kearns struck out the case, saying there was no evidence that the clinic or the UK agent had directed their services towards the Irish market.
Ms Harkin will now have to take a case in England or Poland, or both.
