Prevalence and Microbiological Characteristics of Bacterial Prostatitis in Patients with Erectile Dysfunction

Background: Prostatitis is common in men and causes physical discomfort and pain which suggested to have an impact on sexual dysfunction, including erectile dysfunction. Objectives: To identify the prevalence of bacterial prostatitis (BP) among Egyptian erectile dysfunction (ED) patients. Also, to identify the causative bacterial species. Methodology: A total number of 397 men with ED were included. Three samples were taken from each patient; two urine and one expressed prostatic secretion (EPS); which were subjected to bacterial culture as well as PCR (for Chlamydia trachomatis) with subsequent sensitivity test in case of positive cultures. Results: BP was diagnosed in 94/397 patients (23.7%) (92 cases were diagnosed by culture and 2 cases by PCR). There was no significant difference in the clinical data between ED patients with and without BP, except for age and lower urinary tract symptoms. The most common isolate was E. coli (46.8%). Antibiotic sensitivity revealed that the most effective tested class in decreasing order are; levofloxacin (81.5%), ciprofloxacin (75. %) norfloxacin (73.9%), nitrofurntation (69.6%) and cotrimoxazol (31.5%). Conclusions: In ED patients, 23.7% was found to have BP. The commonest isolates were E. coli followed by S. aureus and E. fecalis. The majority of the isolates were sensitive to levofloxacin, ciprofloxacin and norfloxacin.
