Answer

Renal calculi, renal tubular acidosis, and osteomalacia, nephrogenic diabetes insipidus, and hypokalemia can occur secondary to tubular damage caused by interstitial nephritis, the most common form of renal involvement in Sjögren syndrome.

Interstitial cystitis, with symptoms of dysuria, frequency, urgency, and nocturia, is strongly associated with Sjögren syndrome. [47, 48]

Glomerulonephritis can be caused by Sjögren syndrome but is uncommon and is usually attributable to another disorder, such as SLE or mixed cryoglobulinemia.
