With the increasing use of minimally invasive technologies for the treatment of benign prostatic enlargement/lower urinary tract symptoms, clinicians must become familiar with the various treatment effects and complications. Here we present a case of treatment defect after transurethral convective radiofrequency-induced water vapor thermal ablation (REZUM) radiographically identified as a prostatic abscess without consideration that the finding may have represented an anticipated treatment defect. This likely led to an unnecessary surgical procedure. This entity should be recognized by urologists and radiologists alike to avoid such interventions in the future.
