Plain-English summary
This study looked at women in Denmark who had surgery to treat stress urinary incontinence, a condition that causes involuntary leakage of urine. The researchers wanted to see if giving antibiotics during surgery could help prevent a rare but painful complication called mesh exposure, which can happen with certain types of surgical slings. They found that among over 6,700 women, those who had the transobturator sling (tO-MUS) and received antibiotics had a lower risk of mesh exposure compared to those who did not get antibiotics. However, the results were less clear for the retropubic sling (R-MUS), which also showed a lower risk of mesh exposure compared to tO-MUS overall. In conclusion, giving antibiotics during surgery may help reduce the risk of mesh exposure for women using the tO-MUS approach, while the R-MUS approach appears to have a lower risk of this complication.
Abstract
<h4>Introduction and hypothesis</h4>Stress urinary incontinence is a common condition that significantly affects women's quality of life. Minimally invasive mid-urethral slings are the gold standard treatment, offering high cure rates and low complication risks. Although rare, mesh exposure can cause debilitating pain, making prevention essential. Infection may contribute to mesh exposure, but evidence supporting prophylactic antibiotic use is limited. We hypothesized that a single perioperative dose of antibiotics reduces the risk of mesh exposure and that exposure rates differ between retropubic (R-MUS) and transobturator (tO-MUS) sling approaches.<h4>Methods</h4>We included Danish women undergoing primary mid-urethral sling surgery from 2010 to 2018 using nationwide registry data. Cox's regressions were used to assess the risk of mesh exposure by perioperative antibiotic use and sling type.<h4>Results</h4>Among 6706 women, 3991 underwent R-MUS and 2715 tO-MUS, hereof 34 (0.9%) and 53 (2.0%), respectively, experienced mesh exposures; 5178 (77.2%) received perioperative antibiotics, 82% in the R-MUS and 70% in the tO-MUS group. Mesh exposure occurred in 30 (1.6%) patients with antibiotics vs. 23 (2.9%) without. Perioperative antibiotics reduced mesh exposure in the tO-MUS group (adjusted hazard ratio (aHR) 0.5 [95% confidence interval (CI) 0.3-0.9])), whereas the pooled R-MUS/tO-MUS analysis was nonsignificant (aHR 0.77 [95% CI 0.45-1.32]). In the R-MUS group, the effect remained inconclusive due to low precision. R-MUS was associated with a significantly lower risk of mesh exposure compared to tO-MUS (aHR 0.5 [95% CI 0.3-0.7]).<h4>Conclusion</h4>Perioperative antibiotics were linked to reduced mesh exposure after tO-MUS. R-MUS had a lower mesh exposure risk than tO-MUS.
