Summary

Incomplete pelvic autonomic nerve preservation (PANP) during rectal cancer surgery significantly increases the risk of long-term urinary catheterization. Nerve-sparing techniques are crucial for preventing major urinary dysfunction post-surgery.

Area of Science:

  • Colorectal Surgery
  • Urology
  • Oncology

Background:

  • Rectal cancer surgery, specifically mesorectal excision, can lead to urinary dysfunction.
  • Pelvic autonomic nerve preservation (PANP) is a key surgical consideration.
  • Predicting long-term urinary catheterization is important for patient outcomes.

Purpose of the Study:

  • To identify factors predicting long-term urinary catheterization after mesorectal excision.
  • To evaluate the impact of PANP on postoperative urinary function.

Main Methods:

  • Prospective study of 210 rectal cancer patients undergoing mesorectal excision.
  • Documentation of complete, partial, or absent identification of pelvic autonomic nerves.
  • Correlation of nerve identification with major postoperative urinary dysfunction.

Main Results:

  • 8% of patients required long-term urinary catheterization.
  • Incomplete PANP was significantly associated with major urinary dysfunction (P=0.001).
  • Incomplete PANP was identified as a predictive factor (OR 13.8, P=0.002).

Conclusions:

  • Major urinary dysfunction after mesorectal excision is linked to incomplete nerve preservation.
  • Emphasizes the importance of meticulous nerve-sparing techniques in rectal cancer surgery.
