キーワード : Urolithiasis, Lower ureteral stone disease, Ultrasonotomography

Twenty-one cases of lower ureteral stone disease, which was difficult to detect by ordinary X-ray studies, were diagnosed accurately by means of ultrasonotomography. Stone-like echoes were easily detected on the ultrasonotomograms when the ureter of the affected side was dilated.
It is emphasized that such a case should be examined primarily by ultrasonotomography of the lower abdomen before invasive retrograde pyelography.
