A university professor who conducted an ‘independent’ assessment on vaginal tape has admitted he failed to declare £100,000 worth of funding - from a manufacturer of one of the mesh devices.

Professor Mohamed Abdel-fattah, of Aberdeen University, concluded his original report in 2012 but has since published a correction, after another doctor complained to the General Medical Council (GMC).

Abdel-fattah was the lead clinician on a study which assessed two types of transobturator mesh tape (TOT), used to treat female urinary incontinence. He concluded that no patients were suffering from pain three years after undergoing surgery involving TOT.

Professor Abdel-fattah, a mesh expert, has waited seven years since his initial report to declare this funding, but who’s to say that he would have done so if the GMC had not received complaints about his research misconduct?
