A Case of Rectal Cancer Presented with Renal Pelvic Rupture Associated with Ureteral Obstruction Caused by Extramural Cancer Deposits without Lymph Node Structure (EX)

Abstract

A 34-year-old woman presented with abdominal pain and constipation was found to have rectal cancer and left urinary extravasation, and then she was referred to our hospital. Colonoscopy offered the diagnosis of cancer of the sigmoid colon. Retrograde pyeloureterography revealed defluxion of contrast medium from the renal pelvis, so that rupture of the renal pelvis was diagnosed. During surgery, we confirmed the primary lesion and discontinuous intramesenteric tumor of the colon which had invaded the left ureter and the left common iliac artery that caused obstruction of the ureter with resultant rupture of the renal pelvis. We performed high anterior resection with associated resection of the left ureter and part of left common iliac artery. Histopathology revealed the nodule invading the ureter and the common iliac artery to be extramural cancer deposits without lymph node structure (EX).
This paper deals with a case of rectal cancer presented with rupture of the renal pelvis due to EX.
