title: Voiding dysfunction after pelvic colorectal surgery.
abstract: Bladder dysfunction following colorectal surgery may be related to extirpative procedures in the region of the pelvic autonomic plexus. The most common etiology is from autonomic disruption during abdominoperineal or low anterior resections. Contemporary technical modifications have allowed surgeons to achieve oncologic control while preserving the autonomic nerves that innervate the bladder and sexual organs. Although these modifications have resulted in a significant decrease in the incidence of postoperative bladder dysfunction, bladder dysfunction continues to be a source of significant morbidity after surgery. In this patient population, symptoms are not reliable for accurate diagnosis. The use of urodynamics provides objective measurements of bladder and outlet function and are paramount in providing an accurate diagnosis and in recommending treatments. Follow-up and treatment are highly individualized based on urodynamic findings, patient expectations, patient abilities, and family support. This article provides an overview of pertinent neuroanatomy, diagnosis, urodynamic interpretation, and treatment related to bladder dysfunction following pelvic colorectal surgery.
