BACKGROUND Posterior urethral valve (PUV) is life-threatening congenital anomaly of the urinary tract that results in vesicoureteric reflux, recurrent UTI, voiding dysfunction and renal insufficiency if not treat timely. Endoscopic ablation of posterior urethral valves using cold knife or laser is the current gold standard therapy. Many urologists go for repeat cystoscopy to see residual valve ...

PURPOSE 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 (PUVs). It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV, with less hydronephrosis, and a lower incidence of chronic renal insufficiency (5 vs. 30%). Th...

Introduction:Anterior urethral valve (AUV) is a rare congenital anomaly that can cause obstructive uropathy. AUV can lead to variable urinary tract symptoms, and if left untreated, it can result in end-stage renal disease. AUV should be immediately evaluated and managed. Herein, we present a neonate with AUV and diverticulum, who was treated by cystoscopy. Case report:A 11-day-old boy was ref...

BACKGROUND Urethral valves are infravesical congenital anomalies, with the posterior urethral valve (PUV) being the most prevalent one. Anterior urethral valve (AUV) is a rare but a well-known congenital anomaly. AUV and diverticula can cause severe obstruction, whose repercussions on the proximal urinary system can be important. Few cases have been described; both separately and in association...

Posterior urethral valve and vesical calculus are individually among the most common causes of obstructive lower urinary complaints in children. There are very few reports of association between posterior urethral valves and bladder calculus. We report three such cases. This association of the vesical calculi with posterior urethral valves may lead to a delay in the diagnosis of the posterior u...

PURPOSE We reviewed the literature to better elucidate the history behind our understanding of the anatomy, classification and embryology of posterior urethral valves. MATERIALS AND METHODS A directed MEDLINE literature review of the anatomy, classification and embryology of posterior urethral valves was performed. An effort was made to focus on the most frequently cited historical articles a...
