title: Multiple diverticula of the ureter.
abstract: Multiple ureteral diverticula are rare and not previously reported in Scandinavian literature. Various etiologic factors have been considered. In our opinion, it is a congenital abnormality, not in itself demanding specific therapy. Diverticulosis ureteris is not seen at ordinary excretory pyelography, and only occasionally at a high volume excretory pyelography with compression. They are best visualized by retrograde pyelography, and the incidence may, therefore, be higher than hitherto anticipated.
