The ureters begin at the ureteropelvic junction (UPJ) of the kidneys, which lie posteriorly to the renal vein and artery in the hilum. 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.
How do you identify the ureter?
In cases of laparoscopic adnexectomy, the ureter can be identified transperitoneally as it courses over the pelvic brim. When approaching the cardinal ligament dissection during laparoscopic hysterectomy, a few techniques can help ensure that the ureter is sufficiently lateralized.
