Abstract

Multidetector computed tomography (MDCT) and advances in CT urography techniques have enabled vast improvements in the depiction of the ureter. Studies of the ureter can find a wide variety of conditions including congenital defects and anatomic variants (anomalies in the origin, distribution, and distal insertion of the ureter) as well as all benign and malignant causes of focal and diffuse wall thickening (inflammatory and infectious processes, and neoplasms, as well as iatrogenic thickening and postsurgical changes). Other benign processes like ureteral kinking and stenosis due to extrinsic compression of the iliac vessels are also well characterized by MDCT. The aim of this article is to show the spectrum of ureteral variants and disease apart from common entities related to stones.

Resumen

Con la aparición de la tomografía computarizada multidetector (TCMD) y el perfeccionamiento en las técnicas de urotomografía (UT), la evaluación del tracto urinario ha adquirido otra dimensión, obteniendo cada vez una mejor representación del uréter. Cuando el uréter es evaluado podemos encontrar una gran variedad de entidades, que incluyen anomalías congénitas y variantes anatómicas (alteración en el origen, distribución e inserción distal del uréter), todas las causas benignas y malignas de engrosamiento focal y difuso de la pared ureteral, incluyendo procesos inflamatorios e infecciosos, neoplasias, iatrogenia y cambios posquirúrgicos. Otros procesos benignos, como el asa ureteral y la estenosis por compresión extrínseca de vasos iliacos, pueden ser bien caracterizados por TCMD. El objetivo de este artículo es mostrar el espectro de patología y variantes ureterales diferentes a las entidades comunes relacionadas con cálculos.
