Once in a Blue Moon, Congenital Anterior Urethral Diverticulum

Anterior urethral valves (AUVs) are rare congenital anomalies causing lower urinary tract obstruction in children. Although they are referred to as valves, these obstructive structures often occur in the form of a diverticulum. Congenital anterior urethral diverticulum (CAUD) is an uncommon/rare entity in children which can lead to obstructive lower urinary tract symptoms and urosepsis. Over the past 20 years, more than 260 cases have been reported. However, most cases are diagnosed on prenatal ultrasonography (USG) in early life if patients present with bilateral hydronephrosis and/or azotemia. Diagnosis is by ureteroscopy and radiological imaging. Surgical treatment can be open or endoscopic. Here, we report a new case of CAUD and discuss its clinical presentation, diagnosis, and management. A brief review of the literature is also presented.
