Syntopy of ureter[✎ edit | edit source]

  • Runs inferiorly from the apex of the renal pelvis at the hilum.
  • Passes over the pelvic grim at the bifurcation of the common iliac artery.
  • Runs along the lateral wall of pelvis and enters the urinary bladder.
  • Abdominal parts adhere closely to the parietal peritoneum and are retroperitoneal throughout their course.
  • Three constrictions:
    1. At junction between renal pelvis and ureter.
    2. At crossing of brim of pelvic inlet.
    3. During passage through wall of urinary bladder.

Vasculature of ureter[✎ edit | edit source]

  • Abdominal portion: branches from renal arterties, abdominal aorta and common iliac artery.
  • Pelvic portion: branches from superior vesical aa, middle rectal aa, uterine/vaginal (female), inferior vesical artery (male).

Veins: follow the arteries in the same way and drain into renal and testicular (ovarian) veins.
