Complete duplication of ureters is a very rare clinical entity that may either be asymptomatic or present with a variety of clinical findings. In the presented case a 51-year-old Caucasian female underwent an intersphincteric resection for low rectal cancer. Intraoperatively, during the standard bilateral recognition and mobilization of the ureters, complete unilateral duplication of the left ureter was incidentally detected, deriving from a single renal parenchyma. Such a congenital abnormality though constitutes a major risk-factor of accidental ureteral injury during operations including pelvis. Conclusively, meticulous exposure of both ureters combined with surgeons' unceasing awareness constitute the cornerstone of a safe operation.
双侧输尿管完全重复是一种非常罕见的临床情况，可能无症状，也可能伴有多种临床表现。在本病例中，一名51岁的白种女性因低位直肠癌接受了括约肌间切除术。术中，在标准的双侧输尿管识别和游离过程中，偶然发现左侧输尿管完全单侧重复，起源于单一肾实质。尽管这种先天性异常是包括盆腔手术在内的手术中输尿管意外损伤的主要危险因素。总之，仔细暴露双侧输尿管并结合外科医生的持续警惕是安全手术的基石。
