[CT diagnosis in ureteral obstruction. Retrospective analysis].
A retrospective study of 28 CT examinations of obstructed ureters is reported. In 27 patients it was possible to localise the obstructive process by CT; in 25 cases it was possible to determine the cause of the obstruction. It was possible to distinguish between compression from the outside, obstructive causes in the ureter and strictures of the ureteric wall. In 19 patients it was possible, by taking into account the history also, to determine the aetiology. Anatomical and pathological aspects of the ureter are briefly outlined and the mechanism of ureteric obstruction is discussed in relation to the relevant literature. Difficulties in the CT diagnosis of ureteric obstruction are included.
