【Abstract】Objective To explore the incidence of frailty and its influencing factors in the elderly patients with urinary tract infection after surgery for benign prostatic hyperplasia (BPH). Methods A retrospective analysis was made of the clinical data of 150 elderly patients who underwent surgical treatment for benign prostatic hyperplasia and developed urinary tract infection in the People′s General Hospital of Chengmai County from March 2021 to March 2023. According to the incidence of frailty during postoperative hospitalization, the patients were divided into frailty group (n=68) and non-frailty group (n=82). The two groups were compared in preoperative international prostatic symptom score (IPSS) and comorbidities. SPSS statistics 22.0 was used for data analysis. t test orχ2 test was used to compare the groups according to the data type. Multivariate logistic regression was used to analyze the risk factors of frailty in the elderly patients with urinary tract infection after BPH surgery. Results Age, disease course, preoperative IPSS and hospital stay in the frailty group were significantly higher than those in the non-frailty group, and the proportions of patients with chronic comorbidities, alcohol consumption, monthly income < 1 000 yuan, risk of malnutrition or malnutrition were significantly higher than those in the non-frailty group (P<0.05). Receiver operating characteristic (ROC) curve analysis for age, disease course, preoperative IPSS and hospital stay showed a good predictive value for the frailty in the elderly patients with urinary tract infection after BPH surgery, and the area under the curve (AUC) was 0.861,0.988,0.745 and 0.873, respectively (P<0.05). Multivariate logistic regression analysis confirmed that age ≥ 68 years (OR=3.594,95%CI 1.669-7.739), disease course ≥ 2 years (OR=5.459,95%CI 1.985-15.013), preoperative IPSS ≥ 21 points(OR=2.954,95%CI 1.652-5.282), chronic diseases (OR=4.065,95%CI 1.328-12.443), alcohol consumption (OR=4.254,95%CI 1.654-10.941), monthly income < 1000 yuan (OR=1.612,95%CI 1.065-2.440), length of hospitalization ≥ 8 d (OR=1.258, 95%CI 1.005-1.575), malnutrition risk or malnutrition (OR=3.288,95%CI 1.302-8.303) were the risk factors for frailty in the elderly patients with urinary tract infection after BPH surgery. Conclusion The elderly patients with urinary tract infection after BPH surgery have a high risk of frailty, and its occurrence is affected by multiple factors. In the clinical treatment of such patients, attention should be paid to the screening of high-risk groups of frailty for appropriate interventions as early as possible.
