What type of incision would a surgeon make for access to the lower portion of a ureter?

The Gibson incision is particularly suited for accessing the lower portion of the ureter because it provides optimal exposure to the area. This incision is made along the lateral aspect of the abdominal wall, creating a curvilinear cut that facilitates access to the retroperitoneal space where the ureter is located.

In contrast, other types of incisions built for different surgical purposes lack the specific advantages needed to access the lower ureter effectively. The midline incision provides excellent access to abdominal organs but may not offer direct visibility or ease for ureteral work. The paramedian incision, while it enables access to one side of the abdomen, may not allow for the lateral access required for ureteral procedures. Lastly, a McBurney incision is specifically designed for appendectomies and does not provide the necessary exposure for ureteral access. Thus, the Gibson incision stands out as the most appropriate choice for this particular surgical requirement.
