Answer:
Option A, calcium oxalate
Explanation:
It is estimated that around 80% of all renal stones (nephroliths) and or urinary stones (uroliths) are composed of calcium oxalate due to stationary calcium and the increased presence of uric acid within the kidneys as well as other factors and conditions, like infections (e.g. urosepsis), urinary stasis, PKD, immobility or sedentariness, and increased use of antacids, vitamin D, and laxatives.
Renal stones are most commonly composed of calcium oxalate, option A.
Renal stones are mostly composed of a. calcium oxalate
Renal stones, also known as kidney stones, form when there is an excessive accumulation of calcium and oxalate in the urine, leading to crystallization and subsequent stone formation within the kidneys or urinary tract.
Factors such as diet (high oxalate intake), dehydration, certain medical conditions, and genetic predisposition contribute to their development.
While other substances like uric acid, struvite, and cystine can also form stones, calcium oxalate remains the most prevalent type, accounting for approximately 80% of cases of kidney stones.
