Renal Tubular Acidosis
30 year old lady referred by a local GP for renal ultrasound. She is a known case of renal tubular acidosis (distal type) since 6 year ago. Her initial presentation was hypokalemia and she has been on potassium supplement since then. Her potassium level has normalised and her blood urea is within normal limit.
Ultrasound showed two 6mm calculi in the left kidney. Otherwise, both kidneys are of normal size and echotexture.
Renal tubular acidosis (RTA) is a disease that occurs when the kidneys fail to excrete acids into the urine. This makes the patient’s blood acidic. Without proper treatment, chronic acidity of the blood will lead to growth retardation in children, kidney stones, bone disease, chronic kidney disease, and possibly total kidney failure in adult.
The major aim of treatment is to correct the acidosis with sodium bicarbonate or sodium citrate. This will help to reduce the development of kidney stones.
