A hospital is to pay compensation to hundreds of women who were given the wrong treatment for incontinence.
Up to 400 women are suing Liverpool Women's NHS Trust, claiming their incontinence was made worse by surgeon George Rowland.
Mr Rowland, a former consultant urogynaecologist at the hospital, is accused of performing inappropriate operations and giving poor post-operative care.
Of the 400 women suing the Trust, around 70 cases have been processed and, in 50% of these cases the hospital has admitted negligence and offered compensation.
That is according to Ian Cohen from Liverpool law firm Goodmans Law, which is handling most of the claims.
The women, who had pre-existing incontinence problems, all went to Mr Rowland between the mid-1990s and 2007.
Some then underwent unnecessary procedures, some of which were badly done, according to Mr Cohen.
The outcomes of some of the operations had been "life changing" for some patients, he said.
"Some women have gone in with minor symptoms and have been left double incontinent and have come away with very significant problems. It is horrendous."
It is believed to be one of the largest group actions ever taken against an NHS trust and the eventual cost could run up to £10m.
The General Medical Council has now imposed conditions on Mr Rowland's licence to practise and ruled he must not carry out any urogynaecological surgical procedures.
A spokeswoman for Liverpool Women's NHS Trust said that Mr Rowland no longer worked at the hospital.
