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 urethral valves. The diagnosis of posterior urethral valves should be suspected in all children with vesical or urethral calculi who have persistence of symptoms even after removal of the calculi.
