Urinary dysfunction after rectal cancer surgery: Results from a randomized trial comparing mesorectal excision with and without lateral lymph node dissection for clinical stage II or III lower rectal cancer (Japan Clinical Oncology Group Study, JCOG0212)

Mesorectal excision with lateral lymph node dissection is not associated with a significant increase in the incidence of urinary dysfunction. Urinary dysfunction is associated with tumor location and blood loss.
