Urinary Dysfunction in the Rectal Cancer Survivor

Abstract

Improvements in diagnosis and treatment have resulted in significant improvement in survival rates for rectal cancer. This has led to increasing focus on post-treatment quality of life. One common sequela of treatment for rectal cancer is urinary dysfunction, defined as either difficulty voiding or incontinence. This consists of multiple clinical syndromes of distinct etiologies, most commonly dysfunction of the pelvic autonomic nerves or pelvic floor instability. This can vary in both duration and severity, with some patients experiencing transient and mild symptoms, while others experience prolonged functional impairment. A number of treatment options exist, including behavioral, pharmacologic, and surgical interventions. Because of the multifaceted nature of this process, optimal symptom relief requires careful evaluation of the severity and etiology of a patient’s complaints. Ultimately post-treatment urinary dysfunction can have a significant impact on quality of life, and it is important for clinicians to understand both the causes and management of this process.
