A 62-year-old male visited our department complaining of left flank pain and urinary retention on November 6, 1989. Intravenous pyelography showed small stone shadows in bilateral ureters and lower calyx of kidney and the left kidney was not visualized. Endoscopically, calculi were seen in bilateral ureteral orifice. An ureteral catheter could not be passed up from there bilaterally. On November 13, 1989, January 24 and 26, 1990, calculi were passed out spontaneously. Analysis of the stones revealed silica calculus. The patient had a past history of duodenal ulcers. He was administered magnesium silicate and magnesium alminometasilicate as an anti-acid drug for ten years. Sixteen cases of silica calculus in Japan are reviewed.
