A Rare Case of Prostate Abscess With Pyelonephritis in an Adolescent Male.

Prostatic abscess is a rare urological condition in adolescents. We report the case of a 16-year-old male with no significant past medical history who presented with bilateral flank pain, dysuria, and systemic signs of infection. Imaging revealed bilateral pyelonephritis and a prostatic abscess. Initial conservative treatment with intravenous antibiotics alone showed no improvement, prompting ultrasound-guided transperineal aspiration of the abscess under general anesthesia along with antibiotics. The patient showed marked clinical improvement and was discharged. This case highlights the importance of including prostatic abscess in the differential diagnosis for adolescent males with persistent urinary symptoms and sepsis. It demonstrates the efficacy of transperineal drainage as a relatively safe and minimally invasive intervention in this population.
