title: Pyonephrosis Caused by Salmonella Typhi: A Case Report.
abstract: BACKGROUND
  Salmonella is a rare cause of urinary tract infections. We report here a unique case of pyonephrosis due to Salmonella Typhi (S. Typhi) complication, a stone-related obstructive pyelonephritis.
  
  
  METHODS
  A 47-year-old man, without any history of typhoid fever or gastrointestinal symptoms, presented with a pyonephrosis and life-threatening bacteremia following an acute obstructive right pyelonephritis caused by S. Typhi. The patient was treated by urinary drainage (ureteral stent), antibiotics, and delayed right nephrectomy. We postulated that urolithiasis could explain asymptomatic chronic urinary carriage of S. Typhi.
  
  
  CONCLUSIONS
  S. Typhi is one possible cause of life-threatening urinary tract infection, especially in the context of urolithiasis.
