The Liverpool Women’s NHS Foundation Trust in the UK could end up paying about £20m in compensation for allowing consultant George Rowland to continue performing bladder operations to meet Government targets, despite his high rate of post-operative complications.

The number of women seeking damages at present is 200 while investigations indicate there were problems with 30% of Rowland’s 1,500 cases, and many patients treated were left with chronic pain and weaker bladders following his interventions, investigators said.

The independent report said Rowland, who performed surgery on women between 2000 and 2007 while working at the Aintree Centre for Women’s Health, over-diagnosed women as suffering from stress incontinence and performed unnecessary surgery.

The consultant, who was suspended by the Trust in 2008, claims he felt overwhelmed by his work load and that was the reason for his failed operations.
