Noncompliant bladder resulting from posterior urethral valves

We report on 4 boys with abnormally functioning, poorly compliant bladders and residual urine associated with posterior urethral valves. All 4 boys have been managed with clean intermittent self-catheterization and have shown stabilization or improvement in renal function, and improvement in upper tract drainage and urinary continence. The pathophysiological findings of this type of bladder dysfunction are discussed.
