title: The Whitaker test.
abstract: Since obstruction can be satisfactorily defined only in dynamic terms, it is not surprising that in a difficult case, a dynamic means of investigation is needed. The dynamic approach described in detail has been proved to be of great value in a variety of clinical situations. Further, both the apparatus and the technique are well within the scope of any urologist with access to radiologic equipment.
