Complications of intestinal augmentation and substitution cystoplasty.

The content of these papers has been heavily weighted towards reconstructions performed utilizing segments of stomach. This was not done to place a value judgment on this type of reconstruction, rather it helps establish an awareness of: (1) potentially serious metabolic and gastrointestinal complications not previously reported in children and (2) particularly frequent symptomatic disturbances collectively included in the hematuria-dysuria syndrome. Recognition of problems specifically associated with a certain type of intestinal segment, as well as complications generally accompanying any form of intestinal reconstruction, will hopefully provide pediatric urologists and nephrologists with a better understanding of the issues that must be addressed in using these newer surgical techniques and focus attention on the specific indications and contraindications for incorporating intestinal segments into the urinary tract. Although long-term follow-up information still remains sparse, it appears that regular surveillance programs are required and both pediatric nephrologists and urologists need to be part of these programs.
