A congenital anterior urethral diverticulum (CAUD) is a rare congenital anomaly associated with deficiency of the ventral part of the proximal corpus spongiosum, which creates an out-pouching of urethra that fills during micturition and obstructs the urethral flow. It may be classified as congenital or acquired. Although congenital variety is less common, it can occur as an isolated entity or in association with an anterior urethral valve, which can cause severe obstruction of the lower urinary tract and may also damage the upper urinary tract with serious repercussions [1–3]. However, most cases are diagnosed on prenatal ultrasonography (US) in early life if patients present with bilateral hydronephrosis. The clinical presentation of CAUD is highly variable, depending on the child’s age and the degree of obstruction [6]. Variable treatment choices, endoscopic or open interventions with variable out- comes, have been previously reported in the literature [7].
