Incomplete bilateral duplication of the ureters identified during cytoreductive surgery for ovarian cancer: A case report | International Journal of Surgery Case Reports

Abstract Introduction Incomplete bilateral ureteral duplication is a very rare condition. Ureteral duplication is often asymptomatic or may be associated with several urinary tract complications. Case Report We report a case of a 72- year- old Caucasian female who was referred to our clinic after she was diagnosed with FIGO IIIc ovarian cancer with peritoneal metastases. The patient underwent Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy. During the standard bilateral recognition of the ureters, intraoperatively, incomplete duplication of both of the ureters was identified. Bilaterally, the ureters were derived from a single renal parenchyma and duplication of the pyelocaliceal system in each kidney. Discussion The incomplete bilateral duplication of the ureters is a rare congenital renal abnormality. In a series of 51.880 autopsies ureteral duplication was observed in 0.66% of the cases, while in another autopsy series the ureteral duplication rate was 0.68%. Conclusion Anatomical varieties of the ureter are of utmost importance for the surgeons, because they increase the possibility of iatrogenic ureteral injury. Ureteral injuries are severe complications of pelvic operations and may increase morbidity and even cause mortality.
