<prompt> All are true about Renal tubular acidosis except.Impaired acid productionImpaired bicarbonate resorptionInability to acidify urineNephrolithiasis  <response>: Renal tubular acidosis type 2 is characterized by PCT damage and inability to reabsorb bicarbonate resulting in bicarbonaturia. The damage to DCT in A 1 leads to an inability to acidify urine due to damage to H K antipoer The concomitant calcium loss in urine leads to nephrolithiasis and rickets.
