Prevalencia de infección del tracto urinario recurrente en adultos mayores con hiperplasia prostática benigna atendidos en el Hospital Naval de Guayaquil en el periodo 2022-2024.

Abstract

Introduction: Benign prostatic hyperplasia (BPH) is one of the most common urological conditions among older adults and may contribute to the development of recurrent urinary tract infections (UTIs), whose prevalence in the local context remains poorly understood. Objective: To determine the prevalence of recurrent urinary tract infections in older adults with benign prostatic hyperplasia treated at the Naval Hospital of Guayaquil during the 2022–2024 period. Methodology: An observational, descriptive, cross-sectional, and retrospective study was conducted based on the analysis of 150 medical records of patients older than 65 years diagnosed with BPH, selected through census sampling. Sociodemographic variables, comorbidities, urological complications, microbiological profile, BPH grade, and prostate volume were analyzed. The prevalence of recurrent UTI and its 95% confidence interval were calculated. Results: The mean age was 74.8 ± 6.3 years. The prevalence of recurrent UTI was 30.0% (95% CI: 23.2–37.8), with two episodes per year being the most frequent pattern (60.0%). Hypertension (64.7%) and type 2 diabetes mellitus (36.0%) were the most common comorbidities, while urinary retention was the predominant urological complication (32.0%). Escherichia coli was the most frequently isolated microorganism (57.8%), and grade II BPH was the most common (37.3%). Conclusion: Recurrent UTI affected a considerable proportion of older adults with BPH and was descriptively associated with a higher degree of hyperplasia and greater prostate volume, highlighting the need for clinical and microbiological surveillance in this population.
