Correct preoperative diagnosis of multilocular cystic nephroma is difficult. The decisive feature is visualization of a predominantly cystic process, which, however, might simulate a solid/cystic formation on CT and ultrasound examinations owing to the presence of multiple interspaces. The visualization of cysts in septa requires optimal CT and ultrasound techniques.

In a retrospective analysis of fourteen digital subtraction angiographies and phlebographies on 12 children during the last 18 months the diagnostic accuracy and safety were evaluated. Accurate diagnosis was possible in all cases and no complications occurred. The subtraction procedure most likely could not be replaced by other modes of investigation. It is superior to conventional angiography and phlebography and can be performed quickly and safely.

A modified double-contrast technique has been used as a routine examination instead of the barium enema and the double-contrast technique a.m. Welin. The number of polyps reflects the quality of the technique and the method showed a polyp rate of 4,6%. This is a considerable increase of diagnosed polyps compared to the barium enema, but an improvement in the diagnosis of polyps can be achieved by improving the cleansing procedure prior to the examination.
