The clinical features and biochemical profile of 10 patients with Renal Tubular Acidosis (RTA) were described. The commonest mode of presentation was muscular weakness due to severe hypokalaemia in 5 patients while the other 5 presented with renal colic, haematuria or passage of gravel. Nine patients had nephrocalcinosis on X-rays and one had rickets. All the patients had Type I RTA, 2 of whom presenting initially with Incomplete Type I RTA which progressed to Complete Type I RTA. Two other patients had associated features of proximal tubular involvement evidenced by hypophosphatemia, hypouricemia, hyperphosphaturia, aminoaciduria and glycosuria. Six of the 10 patients had secondary RTA: 2 associated with medullary sponge kidneys, 2 with gout, 1 with idiopathic hypercalciuria and hyperuricosuria and the remaining patient with systemic lupus erythematosus.
