Objective: To describe a case of Bardet-Biedl syndrome involving renal failure and retinal dystrophy. Case Presentation and Intervention: A 50-year-old female patient presented to the emergency service with uremic symptoms and metabolic acidosis. Polydactyly, retinitis pigmentosa, obesity, strabismus, nistagmus and renal failure were found. Because she had end-stage renal failure, hemodialysis therapy was started. She has been well for 18 months, without any complication on hemodialysis. Conclusion: Bardet-Biedl syndrome should be considered in patients with polydactyly, retinitis pigmentosa and renal failure.
