Research output: Contribution to journalArticlepeer-review


The sonographic features of normal lower ureters, visualized during routine examination of the pelvis in a series of 40 patients, are described. A comparison with the corresponding excretory urogram was obtained in 18 patients. In the authors' experience, visualization of the ureters is a normal finding that should not suggest stasis or dilatation. Recognition of the ureters, although restricted to the lower segment, can be useful in the evaluation of patients examined for recent or current renal colic in order to assess with greater accuracy the existence of ureteral stones and their position. In addition, knowledge of normal features and of physiological changes could presumably be used in the evaluation of pathological conditions, congenital or acquired, of the ureters.
