title: [Evaluation of urodynamics and continence in bladder augmentations with sigmoids].
abstract: OBJECTIVE
  To evaluate our experience in sigmoid augmentation to manage renal upper tract dilatation and urinary incontinence.
  
  
  METHODS
  Retrospective descriptive study of the augmentation cystoplasties with sigmoid patch. We analyze clinical, urodinamic and surgical parameters.
  
  
  RESULTS
  We have make 30 cistoplasties with a mean age of 10.24 years (3-15 years) with a mean follow up of 8 years (9 months-15 years). The main diagnosis was neurogenic bladder (63,3%) being the main indication for the augmentation the progressive dilatation of the renal upper tract (43,3%). We associate to the procedure the collocation of an artificial sphinter (30%), Mitrofanoff or ureteral reimplantation. There was no major complication. In the urodinamics, the bladders had low capacity, high pression and low compliance. After surgery, urodinamic parameters improve. During follow up, continence improve with more intermittent clean catheterism (median 4/day). Vesical lithiasis was more common late complication with nor acute abdominal surgical illness nor malignancy; 2 patients finished in renal transplantation. Evolution was positive in 66%, and negative in 18,5%.
  
  
  CONCLUSIONS
  Sigmoid augmentation cystoplasty is a good technique, that allows urodinamic and continence improvement. The conscience in the importance of intermittent catheterisms reduces the incidence of complications.
