title: Umbilical grafting in treatment of recurrent stomal stenosis.
abstract: OBJECTIVE
  The continent catheterizable conduit was first described by Mitrofanoff and is a good option for treating patients with urinary incontinence of different etiologies and those unable to perform transurethral self-catheterization. Stomal stenosis is the most common minor complication involved in this procedure and often is not an easily dealt with problem. Stenosis has a tendency to recur, and the surgical approach becomes progressively more difficult because of local fibrosis and retraction. We present our initial experience with a new surgical technique involving umbilical grafting for the treatment of stomal and urethral meatal stenosis.
  
  
  METHODS
  Four female patients who presented with either recurrent stomal or urethral meatal stenosis underwent a new surgical approach with umbilical grafting for treatment. We present the results of this new technique.
  
  
  RESULTS
  The initial clinical results of this innovative technique, at a median of 4 months of follow-up, showed that all 4 patients remained continent and mostly satisfied with their voiding pattern.
  
  
  CONCLUSIONS
  The results of our study have shown that umbilical grafting is a viable option for the treatment of recurrent stomal and urethral stenosis.
