Beginner Blood Supply of the Ureters Quiz

Q1. How is the arterial supply of the ureter best described?

• Supply only from the internal iliac artery
• Supply only from the renal artery
• Segmental supply from multiple nearby arteries
• A single end artery along its entire length

Q2. Which artery commonly supplies the uppermost ureter?

• Splenic artery
• Femoral artery
• Renal artery
• Inferior mesenteric artery

Q3. Which artery commonly contributes to the blood supply of the abdominal ureter?

• Superior thyroid artery
• Middle cerebral artery
• Coronary artery
• Gonadal artery

Q4. Which major vessel can give direct small branches to the abdominal ureter?

• Superior vena cava
• Pulmonary trunk
• Abdominal aorta
• Ascending aorta in the thorax

Q5. Which arterial system is an important source for the pelvic ureter?

• External carotid arterial system
• Internal iliac arterial system
• Coronary arterial system
• Vertebrobasilar system

Q6. Where do small ureteric arteries form an important longitudinal network?

• Inside the ureteric lumen
• Inside the urinary bladder cavity
• Within the ureteric adventitia
• Within renal corpuscles

Q7. Why should the adventitia be preserved during ureteric surgery?

• It forms glomeruli
• It contains the ureteric lumen
• It produces urine
• It contains vessels important for ureteric perfusion

Q8. From which direction do arterial branches generally approach the abdominal ureter?

• From the posterior skin
• Medially
• From inside the lumen
• Laterally only

Q9. From which direction do arterial branches generally approach the pelvic ureter?

• From the renal papilla
• From the ureteric lumen
• Medially only
• Laterally

Q10. How does venous drainage of the ureter generally relate to its arterial supply?

• Veins generally accompany the arteries and drain regionally
• All ureteric veins drain only into the renal vein
• The ureter has no venous drainage
• All ureteric veins drain directly into the portal vein
