The effects of long‐term lithium treatment on kidney function have been intensively studied. Both retrospective and prospective functional studies have shown that prolonged lithium treatment has a profound influence on renal tubular fucntion, and may result in reduced renal concentrating capacity and increased urine volumes. More improtant, long‐term lithium administration at non‐toxic serum levels has little demonstrable or no effect at all on glomerular function. Prospective studies found no evidence of a progressive impairment of renal clearance. Renal biopsy studies have shown significant histopathological changes in patients with acute lithium intoxication, but only a slight degree of morphological injury in patients with no episodes of lithium posisoning. Other factors than lithium may contribute (e.g. analgesic abuse) or predispose (e.g. pyelonephritis) to similar changes. The lithium dosage schedule may represent an important factor.
