What Causes Recurring Kidney Stones When Suffering From Sjogren S Syndrome?

HI. i RECENTLY passed A 7MM STONE (NOT NATURALLY). wHILE THEY WERE BREAKING UP AND REMOVING THE PIECES, LODGED AT THE BASE OF THE URETER, ANOTHER MUCH SMALLER STONE WAS PULLED OUT AS WELL. i SUDDENLY AM PRODUCING STONES QUICKLY, 3 IN 4 MONTHS. i HAVE AN AUTO IMMUNE DISEASE CALLED SJOGRENS SYNDROME. dO YOU THINK THE TWO ARE CONNECTED? MY FATHER DIED IN HIS 40S, HAVING BEEN A STONE FORMER AND ALSO HAVING SJOGRENS.
