Stones are excreted through the urinary stream and are not necessarily soft; their exact texture varies depending on the composition of the stone. Common clinical types of stones include calcium oxalate type, calcium phosphate type, uric acid type, magnesium ammonium phosphate and cystine.
1. Calcium oxalate type: X-ray density is 0.5 (bone = 1.0), calcium oxalate monohydrate has a hard texture, calcium oxalate dihydrate has a brittle texture.
2. Calcium phosphates: X-ray density of 1.0, hard texture, with calcium hydrogen phosphate dihydrate being the hardest.
3. Uric acid: X-ray density of 0.05, dense structure, medium hardness, soft texture.
4. Ammonium magnesium phosphate: X-ray density of 0.2, loose and friable, soft texture.
5. Cystine: X-ray density of 0.15, shiny surface, soft texture.
Generally speaking, the texture of calcium-containing salt stones is harder, and the texture of other types of stones is softer. If the process of discharging stones, pay attention to the presence of hematuria and pain, and if any abnormalities occur, consult a doctor in a timely manner, and standardize the treatment under the guidance of the doctor.
