Aug 4, 2024 · The ureter is a paired fibromuscular tube that conveys urine from the kidneys in the abdomen to the bladder in the pelvis. The ureter is 25-30 cm long and has three parts: The ureter begins its descent to the bladder by running along the medial aspect of the psoas muscle.

This review provides an overview of pathologic ureteral conditions and a systematic approach to interpreting ureteral abnormalities seen at CT urography.

Mar 23, 2023 · Computed tomography of kidneys, ureters and bladder (CT KUB) is a quick non-invasive technique for diagnosis of urolithiasis. It is usually considered the initial imaging modality for suspected urolithiasis in an emergency setting 1 .

Mar 6, 2016 · Today, ureters are examined by computed tomography (CT) more often than with any other modality. Even without intravenous (IV) contrast, the course of the ureter can be followed from the renal pelvis to the bladder in most patients.

Annotated CT KUB outlining the course of the ureters. See article for more information.

Sep 21, 2022 · A computed tomography (CT) urogram is a useful diagnostic tool for detecting conditions that affect your urinary system. It uses a series of X-rays and a computer to produce three-dimensional images of your soft tissues and bones. CT urograms are painless and have minor risks to your overall health. Most people get their results in a few days.

Ureter segmentation is a critical component for computer-aided diagnosis of ureter cancer. COMPASS consists of three stages: (1) rule-based adaptive thresholding and region growing, (2) path-finding and propagation, and (3) edge profile extraction and feature analysis.

Nov 21, 2013 · This article will discuss optimizing CT urography techniques to improve ureteral distention, the CT findings that can suggest the presence of a tumor, and the vital role of 3D technique in diagnosing subtle lesions.

With the widespread implementation of CT urography, it is critical for radiologists to understand normal ureteral anatomy and the varied appearance of pathologic ureteral conditions at CT urography. Pathologic findings at CT urography include congenital abnormalities, filling defects, dilatation, narrowing, and deviations in course.

Jun 2, 2024 · Ureters . From the kidneys, you can follow the ureters down to where they drain into the bladder. Normal ureters have a thin wall and small diameter, which is why they are best evaluated on a CT urogram where they are filled with contrast-mixed urine and easier to see.
