Abstract:
This article reports a rare case of acute pyelonephritis secondary to left ureteral obstruction by a bladder catheter. The patient was 93years old man hospitalized in the hospital emergency department with a 39°C fever and pyuria from an indwelling catheter. Blood test found hyperleukocytosis, inflammatory syndrome and acute renal failure. Diagnosis was confirmed by non-contrast abdominal CT scan showing distal part of the catheter inside left ureteral orifice with ureterohydronephrosis. Treatment consisted in replacing the catheter by a three-way catheter for irrigation and parenteral antibiotics therapy. Clinico-biological evolution was successful and a urinary tract CT scan could be realized at day 9. The left upper urinary tract function was recovered. With a short review of the literature we propose to describe the different procedures to manage those obstructions.
