OBJECTIVE To discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. DESCRIPTION Signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was perfor...

Anterior urethral diverticula are rare in children. Anterior urethral valves and associated diverticulum is the commonly discussed pathological entity in children. There is a lack of awareness among clinicians regarding less common presentations of anterior urethral diverticula in children; which can have a diverse involvement of the urinary tract. This report describes two uncommon presentatio...

Anterior urethral valves is a very rare congenital anomaly of the anterior urethra. It produces symptoms of varied intensity with the most severe ones leading to Urosepsis and renal failure (similar to as in posterior urethral valves) to the milder ones which may not produce any obstruction at all. However unlike the Posterior urethral valves this anomaly has milder and reversible sequelae in m...

Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15-30 times less common than posterior urethral valves. We present a case of AUV diagnosed at 24th gestational week. Ultrasonography and fetal MRI revealed hydronephrotic kidneys with ureteral duplicity, a distended bladder and perineal cystic mass which confirmed dilated anterior urethra in...

An extremely rare association of anterior and posterior urethral valves in the same patient is reported.

Congenital anomalies of the urogenital tract are the most common anomalies found in the foetus, neonates and infants, but anterior urethral valves and diverticula are rare. Here, we present a case with congenital anterior urethral diverticulum associated with patent ductus arteriosus and polydactyly.

Anterior urethral valves are rare anomalies which cause obstructive uropathy in the lower urinary tract of young men. We discuss our illustrative case and review the English medical literature in order to analyze the clinicopathologic spectrum. We propose a hypothesis of embryology of this lesion and present guidelines for its management.
