It has come to the Publisher’s attention that the above published article was missing an ethics statement stating informed consent was sought.
The following statement has been supplied by the author:
Due to this study being a retrospective audit, it was confirmed that patient consent for the use of anonymous clinical information and images for audit purposes had already been obtained by the bladder radiotherapy consent form that all patients signed upon agreeing to have adaptive bladder radiotherapy treatment.
Both the Authors and Publisher would like to apologise for the oversight.
