MBBS QUESTION #10201
Question 1
During abdominal hysterectomy, the uterine artery is ligated close to the cervix. This step carries a well-recognized risk of injuring which closely related structure that passes just beneath the uterine artery ('water under the bridge')?
  • The ureter✔️
  • The obturator nerve
  • The internal iliac vein
  • The round ligament of the uterus
Correct Answer Explanation
The ureter passes directly beneath the uterine artery near the lateral fornix of the vagina/cervix — the classic 'water (ureter) under the bridge (uterine artery)' relationship — making careful identification of the ureter essential before ligating the uterine vessels during hysterectomy.
