Which surgical procedure has the highest incidence of ureteric injury :
**Core Concept**
Ureteric injury is a known complication of surgical procedures in the pelvic region, often resulting from direct trauma to the ureter or its surrounding tissues. The risk of ureteric injury is higher in procedures that involve dissection and manipulation of the ureter or its surrounding tissues.
**Why the Correct Answer is Right**
The correct answer is **hysterectomy**. Hysterectomy, particularly abdominal hysterectomy, is a surgical procedure that involves the removal of the uterus, which is located in close proximity to the ureter. During a hysterectomy, the surgeon must carefully dissect and ligate the ureter to avoid injury. However, despite careful dissection, the risk of ureteric injury remains high, especially in cases where the ureter is not clearly identified or is not properly ligated. The ureter's proximity to the uterus and the surrounding tissues makes it susceptible to injury during a hysterectomy.
**Why Each Wrong Option is Incorrect**
**Option A:** **Appendectomy** is a surgical procedure that involves the removal of the appendix, which is located in the right lower quadrant of the abdomen. While an appendectomy can be a complex procedure, the risk of ureteric injury is lower compared to a hysterectomy.
**Option B:** **Cesarean section** is a surgical delivery procedure that involves making an incision in the uterus to deliver a baby. While a cesarean section can involve dissection in the pelvic region, the risk of ureteric injury is lower compared to a hysterectomy.
**Option C:** **Prostatectomy** is a surgical procedure that involves the removal of the prostate gland, which is located in the male pelvis. While a prostatectomy can involve dissection in the pelvic region, the risk of ureteric injury is lower compared to a hysterectomy.
**Clinical Pearl / High-Yield Fact**
The ureter is most commonly injured during surgical procedures in the pelvic region, particularly during hysterectomy and prostatectomy. To minimize the risk of ureteric injury, surgeons must carefully dissect and identify the ureter during these procedures.
**Correct Answer:** B. Cesarean section
