Summary

Radical rectal surgery can cause bladder and erectile dysfunction. Prospective urodynamic evaluation confirms a small but significant risk of permanent bladder dysfunction, likely due to pelvic nerve injury.

Area of Science:

  • Urology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Rectal surgery for cancer can lead to significant postoperative complications.
  • Previous studies on bladder and erectile dysfunction after rectal surgery have varied due to retrospective designs.

Purpose of the Study:

  • To prospectively determine the incidence of bladder and erectile dysfunction following rectal cancer surgery.
  • To highlight the importance of urodynamic evaluation in assessing these dysfunctions.

Main Methods:

  • Prospective study of 20 patients undergoing rectal cancer surgery.
  • Clinical assessment, uroflowmetry, and video-cystometrography were performed pre- and post-surgery.
  • Patients were monitored for voiding difficulties and erectile function.

Main Results:

  • Pre-surgery, only 6 patients had normal bladder function and 13/16 men were potent.
  • Eight patients developed bladder dysfunction post-surgery, with three showing complete bladder denervation.
  • Three potent men became impotent after surgery.

Conclusions:

  • Bladder and erectile dysfunction are recognized complications of radical rectal surgery.
  • Prospective urodynamic evaluation is crucial for accurate risk assessment.
  • Pelvic nerve injury during surgery is the likely cause of permanent bladder dysfunction.
