title: [Uropathies and nephropathies of Bardet-Biedl syndrome in children].
abstract: BACKGROUND
  The Bardet-Biedl syndrome is an autosomal recessive disease, characterised by obesity, retinal degeneration, hypogenitalism in men, polydactylism and an often moderate mental retardation. With these cardinal features, others clinical findings (secondary features) including diabetes, congenital heart defects, hypertension or syndactyly can be seen. Renal involvement is almost constant, but varies from a moderate impairment of the tubular functions to chronic renal failure caused by malformative uropathy or glomerulopathy.
  
  
  OBJECTIVE
  Report a new cases.
  
  
  METHODS
  We report 6 patients with Bardet-Biedel syndrome who had renal involvement.
  
  
  RESULTS
  Three patients had cystic dysplasia, one patient an increased fractional sodium excretion, one other a vesico-ureteral reflux and the last patient developed end-stage renal failure following acute post streptococcal glomerulonephritis. We insist on precocious diagnosis and multidisciplinary treatment of these renal lesions, to ovoid or, at least, to slow down the evolution to the terminal renal failure, essential prognosis factor.
  
  
  CONCLUSIONS
  Renal involvement, is considered as a major criteria predicting high morbidity and mortality during Bardet-Biedl disease.
