Learning objectives: Review the most common pathology causing ureteral dilatation (UD) and the radiologic appearance. Learn about the ureter embriology
Background: The ureter arises proximally from the renal pelvis at the ureteropelvic junction (UPJ) and empties distally into the urinary bladder at the ureterovesicular junction (UVJ). It remains retroperitoneal throughout its course.
Findings and procedure details: In the fifth week of development, the ureteric bud (UB) arises as a diverticulum from the Wolfian duct. The bud invades the center of the metanephrogenic blastema. The meeting of these two tissues causes changes in the bud and the metanephros. The UB divides and branches forming the renal pelvis, in[...]
Conclusion: Normal 0 false false false PT JA X-NONE UD is a common finding in pediatric and adult groups. The radiologist must be in touch with the most common causes.
