What is urinary calculi?

Urinary calculi are usually caused by metabolic abnormalities, drug factors, local causes, etc. The specific analysis is as follows:

1. metabolic abnormalities

Due to the presence of hypercalcemia, abnormal urine pH, hypercalcuria, etc., it is easy to cause compounds and different ions to combine to form precipitates, which can easily cause urinary calculi over time.

2. Drug factors

Due to the long-term use of a large number of drugs such as triamterene tablets, sulfadiazine tablets, sulfasalazine enteric-coated tablets, etc., the ingredients contained in the above drugs will provide the substances required for the growth of calculi, resulting in urinary calculi.

3. Local causes

Due to the presence of urinary tract foreign bodies, urinary tract infections, urinary tract obstruction, etc., it will affect urine components, causing a large number of crystals to precipitate, resulting in urinary calculi.
