Kidney stones are chunks of material, usually calcium compounds, that form in the kidney and can become lodged in the ureter, which leads from the kidneys to the bladder. Once â¦ a stone passes, or is dislodged or broken up, it can be captured from the urine by a filter cone, and returned to a urologist for examination.

Debridement is the medical removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue.

In oral hygiene and dentistry, debridement refers to the removal of plaque and calculus that have accumulated on the teeth. Debridement in this case may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen peroxide.
