Sexual and urinary dysfunction after proctectomy for rectal cancer

Abstract

Sexual and urinary dysfunction occur frequently after rectal surgery. Total mesorectal excision (TME) is currently the optimal technique for resection of rectal cancer, providing superior carcinological and functional outcomes. Age, pre-operative radiation therapy, abdominoperineal resection, and surgery which fails to respect the "sacred planes" of TME are the four major risk factors for post-operative sexual and urinary sequelae. In the era of TME, postoperative sexual dysfunction ranges from 10-35%, depending on the scores used to assess it, while urinary sequelae have decreased to less than 5%. The place of laparoscopic surgery remains to be defined, particularly with respect to these complications. It is essential to inform the patient pre-operatively about the possibility of such disorders not only for patient informed consent but also to help with correct post-operative management of the problem. Management is multifaceted, and includes psychological, pharmacological, and sometimes surgical therapy.
