Urinary and sexual dysfunction after rectal cancer surgery: A surgical challenge

This manuscript focused on the surgical challenge of urinary and sexual dysfunction after rectal cancer surgery based on the interesting results demonstrated by the observational study of Chen et al, which was published in the World Journal of Gastrointestinal Surgery. Urinary dysfunction occurs in one-third of patients treated for rectal cancer. Surgical nerve damage is the main cause of urinary dysfunction. Radiotherapy seems to exacerbate sexual dysfunction. The role of Denonvilliers' fascia preservation vs resection when performing total mesorectal excision (TME), the impact of robotic and transanal TME, alternatives to open and laparoscopic TME, as well as intraoperative pelvic neuromonitoring are discussed in this report. In conclusion, exact knowledge of the highly complex pelvic neuroanatomy and the use of novel surgical techniques can lead to a reduction in urinary and sexual dysfunction after rectal cancer surgery.
