Acute urinary retention (AUR) is a common urological emergency characterized by a sudden inability to pass urine. In this manuscript, a 58-year-old male with the history of AUR caused by a prostatic urethral polyp, which is a rare cause of AUR in elderly, was presented. In this patient, polyp resulted in complete urethral obstruction with a mechanism similar to that of posterior urethral valves and transurethral resection of prostate and this polyp improved the infravesical obstruction symptoms completely and rapidly.
Key Words: Acute urinary retention, Prostatic urethral polyp, Posterior urethral valve, Transurethral resection, Cystoscopy.
