Autonomic nerve preservation (ANP) during rectal cancer resection is based upon a
comprehensive understanding of pelvic surgical anatomy and the effects of nerve injury
on genitourinary dysfunction. Techniques that combine ANP with radical rectal cancer
resection developed over the last 20 years have reduced the risk of sexual and bladder
dysfunction without compromising oncologic results. In this article, a detailed description
of the operative techniques currently employed is highlighted by comments and figures
of the pertinent pelvic anatomy. The results of genitourinary function subsequent
to nerve-preserving rectal cancer surgery are also presented.
