Maximum chances of ureteric injury are with;
**Core Concept**
During pelvic surgery, ureteric injury is a potential complication due to the close proximity of the ureters to various structures, including the uterine arteries, ovaries, and the pelvic sidewall. The ureters are susceptible to damage due to their tortuous course and the lack of a peritoneal covering in the lower third of their course.
**Why the Correct Answer is Right**
Ureteric injury is most likely to occur during hysterectomy, particularly when the uterine arteries are ligated and divided. This is because the ureters are closely associated with the uterine arteries in the parametrium, and damage to the ureters can occur if the uterine arteries are not properly identified or ligated. Additionally, the ureters are more likely to be injured during hysterectomy due to the increased complexity of the procedure and the need for more extensive dissection.

**Clinical Pearl / High-Yield Fact**
To minimize the risk of ureteric injury during pelvic surgery, it is essential to identify and preserve the ureters throughout the procedure. This can be achieved by using intraoperative fluoroscopy or a ureteral stent to visualize the ureters and by maintaining a clear understanding of the ureteral anatomy.
**Correct Answer:** C.
