[Urethral lengthening (the Kropp technic) in neurologic urinary incontinence in children and adolescents. Results of a series of 22 cases].

In 1986 Kropp et Angwafo described a technique of urethral lengthening for the treatment of urinary incontinence in children with neurogenic bladders. We have used a modified version of this procedure in 22 girls between 1986 and 1990. Here we report its mid and long term effects on continence. The problems we have encountered in these patients are discussed.
