Male sex and anterior wall tumor location as risk factors for urinary dysfunction after laparoscopic rectal surgery
- 8 Downloads
Total mesorectal excision (TME) has decreased the local recurrence rate and improved the overall survival of rectal cancer patients. However, urinary dysfunction remains a clinical problem after rectal cancer surgery. The aim was to assess the risk factors for postoperative urinary dysfunction.
This study was a single-center, retrospective analysis of 104 patients who underwent laparoscopic rectal surgery between November 2016 and October 2017. Postoperative urinary dysfunction was defined as the need for urinary catheter re-insertion or the presence of residual urine (≥ 150 mL) postoperatively.
Postoperative urinary dysfunction was seen in 18 patients (17%). Multivariate analysis showed that male sex (odds ratio 3.89, p = 0.034) and anterior wall tumor location (odds ratio = 4.07, p = 0.037) were the predictors of postoperative urinary dysfunction. Compared with patients without risk factors, those with the two risk factors needed longer hospital stays (16 days vs. 30 days, p = 0.0022).
Male sex and anterior wall tumor location were the risk factors for urinary dysfunction after laparoscopic rectal surgery.
