Abstract

We report a case of a 64-year-old male with right pyonephrosis due to ureteral stones in association with chronic renal failure. The patient had been treated with hemodialysis for fourteen years. He was admitted to the Department of Internal Medicine of Kurobe City Hospital with chief complaints of fever and lumbago in January 2013. CT demonstrated a right pyonephrosis accompanied by right ureteral stones positioned in the middle and lower ureter. The stones could not be detected by KUB. He was consequently referred to the Department of Urology. Firstly, percutaneous nephrostomy for the right kidney was performed, and 200 ml of pyuria was discharged at that time. Urine culture demonstrated Escherichia coli. Secondly, rigid transurethral ureterolithotripsy (TUL) for the right ureteral stones was performed using Lithoclast, and a ureteral stent was indwelled on day 15 after nephrostomy construction. The nephrostomy catheter and ureteral stent were removed 10 and 21 days after the operation, respectively. The constituents of the stone were CaOx (26%) and CaP (74%). Right hydronephrosis improved and the patient showed no pyelonephritis for 1 year postoperatively.
