Abstract

BACKGROUND

Crossed renal ectopia (CRE) occurs when one kidney crosses the midline from the primary side to the contralateral side while the ureter remains on the primary side. Rectal cancer, one of the most common malignant tumors of the digestive tract, refers to cancer from the dentate line to the rectosigmoid junction. The concurrent presentation of CRE alongside rectal cancer is an uncommon clinical observation.

CASE SUMMARY

Herein, we report a 69-year-old male patient with rectal cancer who was diagnosed with CRE via computed tomography during hospitalization. Following thorough preoperative evaluations, the patient underwent Dixon surgery.

CONCLUSION

We performed laparoscopic radical resection of rectal cancer and adequate lymph node removal in a patient with CRE with no postoperative discomfort.

Keywords: Rectal cancer; Crossed renal ectopia; Anatomy; Laparoscopic surgery; Case report

Core Tip: Rectal cancer is a common malignant tumor in clinical practice, and current treatment methods mainly include surgery and chemotherapy. The occurrence of rectal cancer in conjunction with crossed renal ectopia (CRE) is exceedingly rare. We reported a patient with rectal cancer who underwent CRE and Dixon surgery.
