title: A simple classification of wide ureters.
abstract: A simple classification of abnormal ureters is presented which categorises the ureters according to the presence or absence of 3 factors, namely reflux, bladder outlet obstruction and ureteric obstruction. It has been devised to try to rid the literature of many confusing and obsolete terms and it is hoped that this new classification may become internationally accepted.
