Predicting Pain Levels Following Vaginal Reconstructive Surgery: Who Is at Highest Risk?

An ability to anticipate individuals at increased risk of postoperative pain would improve coordination of care and patient satisfaction. We sought to describe predictive factors of postoperative pain following vaginal reconstructive surgery.

This institutional review board-approved, retrospective study used previously collected data from research performed at 1 center from 2009 to 2015. Eligible trials enrolled subjects undergoing vaginal reconstructive surgery for pelvic organ prolapse. All studies used a validated visual analog scale (VAS) for pain on postoperative day 1. Other information collected included pain medication use, medical and surgical history, and demographics. Linear regression analyses, multiple regression analyses, Mann-Whitney U, and Kruskal-Wallis tests were used to analyze the relationship between VAS scores and other variables.

Six studies were analyzed with a total of 364 patients. The median age was 60 years (interquartile range, 16 years), and the median pain score on postoperative day 1 was 35 mm on a 100-mm VAS. Patients younger than 60 years (P < 0.001), those who used tobacco (P = 0.014), those who used pain medication prior to surgery (P = 0.007), and those who did not have a concomitant midurethral sling (P = 0.018) had significantly higher pain scores postoperatively. A trend was also noted with operating times greater than 210 minutes (P = 0.057) and preexisting history of depression (P = 0.065). Multiple regression was performed, and age, depression, tobacco use, and concomitant sling were found to be independent factors predictive of postoperative pain scores.

Age, depression, tobacco use, and concomitant midurethral sling are significant independent factors predictive of postoperative pain following vaginal reconstructive surgery.
