title: From red to white urine: a patient's nightmare with a rather benign outcome.
abstract: BACKGROUND
  Chyluria is a medical condition with presence of chyle in the urine. The disease is most prevalent in endemic regions of Africa and the Indian subcontinent where it is mostly caused by parasitic infections, particularly lymphatic filariasis due to wucheria bancrofti. Non-parasitic chyluria, however, is a very rare finding.
  
  
  METHODS
  We report the case of a 48 year old woman who developed a lymphorenal fistula with chyluria following ureterrenoscopy with biopsies taken for urological work-up of persistent macrohematuria. Renal biopsy confirmed the diagnosis of benign familial hematuria due to thin basement nephropathy, a condition frequently associated with episodes of macrohematuria.
  
  
  CONCLUSIONS
  This case highlights a rare case of non-parasitic chyluria as a complication of urological work-up for macrohematuria of benign nature.
