Abstract
The major postoperative complications in rectal surgery are urinary retention and urinary tract infection. Although the pelvic autonomic nerve preserving procedure is performed, urinary dysfunction may still occur. In this article, we report a patient with rectal cancer who developed a postoperative urinary tract infection (UTI). An insufficient estimation of bladder function and frequent periodical bladder catheterizations were considered to be the cause of the UTI. In conclusion, the careful management of urinary tract complications is required in patients undergoing surgery for rectal cancer.
