Stone types

a) Calcium stones

All urinary tract stones contain 80-85% calcium. Calcium stones depend mostly on the decrease in calcium, uric acid, oxalate elevation and citrate levels.

b) Non-calcium stones

1. Struvite

Magnesium is ammonium phosphate stones. Mostly seen in women. It may recur quickly. The struvite stones are formed by bacteria that break down proteas, pseudomonas, klebsiella and mycoplasma-like urea. Urine pH is alkaline. It is above pH 7.

It is impossible to sterilize these stones with antibiotics.

Removal of the stone and treatment of the infection give successful results.

2. Uric acid

All urinary tracts account for less than 5% of the stones. It is more common in males. Uric acid is high in the urine. It is common in people with gout disease and myeloproliferative disorders. Elevated uric acid may be due to excessive purine intake. The urine is acidic.

3. Cystine

It is due to the absorption of abnormal bowel mucosa. An inherited metabolic disorder that causes tubular absorption of dibasic amino acids (ornithine, lysine, arginine) causes cystine stones. Urinary tracts form 1-2% of the stones. The formation of cystine stones is entirely due to excessive cysteine ​​excretion.

4. Xanthine stones

Congenital xanthine oxidase develops due to enzyme deficiency.

5. Indivvir stones

In patients with acquired immunodeficiency syndrome, protease inhibitors are effective and popular treatments. Radiosaydamy stones.

6. Rare

Silicate stones are rare and are usually due to long-term uptake of silica containing antacids such as magnesium silicate and magnesium aluminometasilicate.
