Factors associated with and preventive strategies for urinary tract infections after ovarian cancer cytoreductive surgery
Objective To analyze the factors associated with urinary tract infections(UTIs)after laparoscopic ovarian tumor reduction operation(OTRO)and to explore relevant nursing strategies.Methods A retrospective study was conducted on 228 ovarian cancer patients who underwent laparoscopic OTRO at our hospital from October 2019 to October 2022.Patients were allocated to an infection group and a non-infection group based on the presence of postoperative UTIs.Clinical data were collected and compared between the two groups.Multivariate logistic regression analysis was used to identify independ-ent risk factors for UTIs.Results Postoperative UTIs occurred in 61 of 228 patients,with an infection rate of 26.75%,mainly presenting with urinary irritation and fever.The infection group had significantly older patients,more intraoperative blood loss,longer catheterization,and longer hospital stays compared to the non-infection group(P<0.05).Factors such as diabetes,advanced tumor stage(ⅢC-ⅣA),more than two catheter insertions,cleaning the urethral orifice 1-2 times/day,changing urine bags ≤1 time/day,and postoperative hypoproteinemia were significantly more prevalent in the infection group(P<0.05).Independent risk factors for UTIs included diabetes,advanced tumor stage,prolonged catheterization,and postoperative hypoproteinemia(P<0.05),while higher frequency of urethral orifice cleaning was a protective factor(P<0.05).Conclusion The occurrence of UTIs after laparoscopic OTRO in ovarian cancer patients is associated with mul-tiple factors.Diabetes,advanced tumor stage,prolonged catheterization,and postoperative hypoproteinemia are independent risk factors,while frequent urethral cleaning is a protective factor.Targeted nursing measures based on these findings can help prevent UTIs.
