Objective: Pelvic kidney is the most common congenital renal anomaly with an incidence of 1 in 1,000 to 1 in 2,000. A pelvic kidney can be encountered at pelvic or paraaortic lymphadenectomy. Case: A 70-year-old female patient undergoing pelvic-paraaortic lymphadenectomy due to serous endometrial cancer. Due to the known right pelvic kidney, lymphadenectomy was more difficult and gentle. Conclusion: Preoperative evaluation of the pelvic kidney is important to avoid any complications during surgery. Lymphadenectomy should be more careful in patients with pelvic kidney.
