THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The ureter originates in the renal pelvis and leaves the kidney through the hilus, located at its medial border (Fig. 7-2). The ureter follows a caudal path that is retroperitoneal in the abdominal portion. At the level of the pelvic cavity, the ureter opens into the urinary bladder.

Detailed explanation-2: -The ureters begin at the ureteropelvic junction (UPJ) of the kidneys, which lie posteriorly to the renal vein and artery in the hilum[1]. The ureters then travel inferiorly inside the abdominal cavity. They pass over (anterior to) the psoas muscle and enter the bladder on the posterior bladder aspect in the trigone.

Detailed explanation-3: -The hilus is the point of entry and exit of the renal arteries and veins, lymphatic vessels, nerves, and the enlarged upper extension of the ureters.

Detailed explanation-4: -Expert Answer. The structures that enter and exit the renal hilum are-Ureters, renal arteries, and renal veins.
