In this prospective observational study, we aimed to evaluate the consequences of laparoscopic fascia space priority lymph node dissection on urination and sexual function.

To assess the consequences of laparoscopic lateral lymph node dissection (LLND) using the fascial space priority approach on urinary and sexual function in patients with advanced middle and low rectal cancer.

Material and methods
Consecutive patients undergoing laparoscopic LLND using the fascial space priority approach from December 2020 to November 2022 were identified from Tianjin Union Medical Center. Clinical data including patient characteristics, surgical details, and pathology were analysed. The urinary function was assessed by international prostate symptom score (IPSS) questionnaire and residual urine volume. The sexual function was investigated using the international index of erectile function (IIEF) questionnaire.

A total of 51 patients, mean age 60.5 ±10.9 years, were identified. The lymph nodes were positive in 70.6% (36/51) of the patients. There was no significant difference between the preoperative IPSS score and that at 6 months (5.2 ±2.1 vs. 5.6 ±1.5; p = 0.16). And there was no significant difference between the residual urine volume and that at 6 months (9.5 ±10.6 vs. 8.6 ±6.3; p = 0.61). The IIEF score before the surgery showed no significant difference from that at 6 months after the surgery (21.1 ±2.2 vs. 20.6 ±2.3; p = 0.26).

Laparoscopic LLND using a fascial space priority approach can effectively protect the autonomic nerves. The procedure reduces short-term urination and sexual function, but it has little effect on long-term function.
