The incidence of ectopic kidney is approximately 1:1,000 in newborns. Ectopic kidney has a place outside of renal fossa and been found in the pelvis, abdomen, and thorax. We reported a case of a 51-year-old female who was referred to our hospital with the complaint of abnormal vaginal bleeding and pelvic pain. Adenocarcinoma of cervix was reported after biopsy, radical hysterectomy and bilateral salphingo-oopherectomy with pelvic and para-aortic lymph node dissection were performed. Unilateral, right renal ectopic kidney with vessels was observed during paraaortic lymphadenectomy in cervical cancer surgery. During gynecological oncologic surgery especially at the retroperitoneal stage congenital organ abnormalities must be kept in mind and surgery must be planned according to the abnormalities.
