Voiding disorders and unstable bladder in children.

A total of 42 neurologically normal children with different voiding problems have been studied urodynamically during the last 4 years. Seventeen patients had unstable bladder, with significantly decreased capacity. The degree of volume decrease depended on the severity of instability and on the type of micturition problems. Eight patients had trabeculation of the bladder wall and 2 had wide bladder neck. Six children had vesicoureteral reflux in 8 ureters. Eleven patients were treated with Ditropan. Four children had repeated cystomanometry after treatment. They had stable bladder and its capacity has increased.
