RESUMO
OBJECTIVE: The aims of the study were to determine the rate of urinary tract infection (UTI) in women undergoing colpopexy and to evaluate risk factors and timing for postoperative UTI. METHODS: This was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2017. Patients were grouped into those with and without UTI. Pairwise analysis between groups was performed using χ2 and Fisher exact test. Multivariable logistic regression was used to identify independent predictors of UTI. RESULTS: Of 23,097 women who underwent colpopexy, 1079 (4.7%) experienced a postoperative UTI. Urinary tract infection was most frequently diagnosed in the second week after surgery (38.2%), compared with week 1 (19.9%), 3 (22.8%), and 4 (19.1%) (P < 0.001). Patients diagnosed with a UTI were more likely to have insulin-dependent diabetes (2.8% vs 1.7%, P = 0.006), coagulopathy (1.3% vs 0.7%, P = 0.04), and chronic steroid use (2.7% vs 1.8%, P = 0.004). Patients with a UTI versus those without a UTI were more likely to have undergone an intraperitoneal or extraperitoneal vaginal colpopexy (37.8% vs 30.5%, P < 0.001) and (29.8% vs 25.6%, P = 0.003), respectively, and more likely to undergo combined anterior and posterior colporrhaphy (17.1% vs 12.2%, P < 0.001). After logistic regression, intraoperative cystotomy repair (adjusted odds ratio = 2.93, 95% confidence interval = 1.54-5.59) was the most significant risk factor. CONCLUSIONS: Postoperative UTI after colpopexy occurred less frequently than previously reported. Vaginal colpopexy is associated with a higher risk of UTI than abdominal or laparoscopic colpopexy.
