Why do ureteral stones occur?
Doctor's answer (1)
Dr. Li Mingchuan
The causes of ureteral stone formation are diverse, primarily including:
1. Diet and lifestyle: Insufficient fluid intake leads to concentrated urine, increasing the risk of stone formation. Excessive consumption of animal protein, salt, and oxalate can also promote stone development.
2. Medication factors: Certain medications such as triamterene and sulfonamides are themselves components of stones, while inappropriate use of drugs like vitamin D can also facilitate stone formation.
3. Metabolic abnormalities: Urine contains various stone-forming substances such as calcium, oxalate, and cystine. Metabolic disorders make these substances more likely to form stones.
4. Local factors: Local conditions such as urinary tract obstruction, urinary tract infections, and ureteral strictures are closely associated with stone formation.
