Abstract

Purpose
This study aimed to determine the treatment modality for prostatic abscesses according to size.
Materials and Methods
Twenty-five patients diagnosed with prostatic abscesses were retrospectively reviewed. All patients were treated with intravenous empirical and appropriate antibiotics according to culture results. They were grouped according to the size of the prostate abscess based on computed tomography results (group A, with prostate abscess ≤2 cm, n=10; group B, with prostate abscess size >2 cm, n=15), and their treatment modality and outcomes were compared.
Results
The prostatic abscess sizes were 1.31±0.37 and 3.49±1.06 cm for groups A and B, respectively. Prostate-specific antigen, prostatic volume, and comorbidity were not significantly different (p>0.05), whereas pelvic pain was significantly different (p=0.028). There was no difference in the microorganisms isolated from urine and blood culture, empirical antibiotics, and broad-spectrum antibiotics between the two groups (p>0.05). More patients in group B underwent transurethral abscess deroofing than those in group A (p=0.040). Patients in group B had a more extended hospitalization period and intravenous antibiotics duration than those in group A (p=0.024 and p=0.013, respectively). Group B had more cases of septic shock, intensive care unit admission, and mortality events than group A (p=0.024, p=0.001, and p=0.061, respectively). However, prostatic abscess recurrence and urological chronic complication did not significantly differ (p>0.05).
Conclusions
Appropriate use of antibiotics is crucial. This study shows that the treatment of patients with prostatic abscess >2 cm is more difficult, but transurethral abscess deroofing can lower mortality, prostatic abscess recurrence, and urological chronic complications.
