Purpose
We conducted a retrospective study to investigate causative bacteria of adult epididymitis and their characteristics and resistance in the recent 10 years at a tertiary hospital.
Materials and Methods: We reviewed the medical records of 121 patients who were diagnosed with acute epididymitis from 2002 to 2012. Diagnosis was based on symptoms, physical examination, and ultrasonography. We analyzed causative organisms and changes of antibiotic resistance pattern according to time course in the recent 10 years.
Results: The most commonly detected bacteria were Pseudomonas aeruginosa and Escherichia coli. Fluouroquinolone resistance has emerged since 2006 and 50% of the patients have resistance to fluouroquinolones.
Conclusions: Quinolone resistance composes a major proportion of the causative organism. Therefore, while according to the guidelines, fluoroquinolone may be the first response for elderly men, we recommend that antibiotic resistance should be considered if fever persists, and other antibiotics could be included.
