Pyonephrosis Caused by Salmonella Typhi: A Case Report.

[typhoid]

Introduction : 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 . Case Report : 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 . Conclusion : S . Typhi is one possible cause of life-threatening urinary tract infection , especially in the context of urolithiasis . © 2014 S . Karger AG , Basel .
