Transrectal Ultrasound-Guided Transperineal Drainage of a Huge Prostatic Abscess: A Case Report with Literature Review A 73-year-old male patient who was suffering from acute urine retention and fever was diagnosed as having a huge prostatic abscess. Transrectal ultrasound-guided transperineal drainage was performed, and adequate drainage was followed-up by pelvic computed tomography. We conclude that transrectal ultrasound-guided transperineal drainage is an effective, minimally invasive treatment for a huge prostatic abscess.
