Risk Factors for Urinary Tract Infection in Gynecological Malignant Tumor Inpatients: A Retrospective Study

Urinary tract infection (UTI) is one of the most common infectious complications in hospitalized patients with gynecological malignancies and may lead to treatment interruption, prolonged hospitalization, increased healthcare costs, and even severe systemic infection. To investigate the incidence of UTI and identify its associated risk factors among hospitalized patients with gynecological malignancies at Meizhou People's Hospital, in order to provide evidence for targeted prevention and optimized clinical management.

This study conducted a retrospective analysis of 659 hospitalized patients with gynecological malignant tumors who were treated at Meizhou People's Hospital in 2024. Clinical data were retrospectively collected, including general baseline data, tumor-related data, treatment-related data, and infection-related data. Univariate analysis and multivariate logistic regression analyses were used to screen the risk factors for UTI.

In terms of tumor classification, cervical cancer accounted for the largest proportion, with 291 cases (44.2%), followed by endometrial carcinoma (201 cases, 30.5%), ovarian cancer (99 cases, 15.0%), and other types of gynecological malignancies (68 cases, 10.3%). Regarding treatment, 341 (51.7%) patients underwent ureteral stenting, 197 (29.9%) patients had an indwelling catheter for ≥7 days, 152 (23.1%) patients received chemotherapy, and 516 (78.3%) patients underwent surgical treatment. The incidence of UTI was 6.5% (43/659). Logistic regression analysis showed that indwelling catheter for ≥7 days (odds ratio (OR) = 4.48, 95% confidence interval (CI): 2.05-9.81, p<0.001), number of deliveries <2 (OR=2.46, 95% CI: 1.08-5.60, p=0.032), obesity (BMI≥28)(OR=3.32, 95% CI: 1.02-10.79, p=0.046) were associated with UTI.

Indwelling catheterization for ≥7 days, number of deliveries <2, and obesity are independent risk factors for UTI in patients with gynecological malignant tumors.
