FOUR-HOUR VOIDING OBSERVATION IN YOUNG BOYS WITH POSTERIOR URETHRAL VALVES

Abstract

Four-hour voiding observation is an easy noninvasive method that focuses on emptying difficulties and clearly detects differences in voiding patterns between boys with posterior urethral valves and healthy, nontoilet trained children. We recommend the method as a complement to standard cystometry for the diagnosis and followup of bladder dysfunction in young boys with posterior urethral valves to identify the need for treatment.
