PATHOLOGY

Detailed explanation-1: -Nephrolithiasis is the term employed for kidney stones, also known as renal calculi, and they are crystal concretions formed typically in the kidney. Calculi typically form in the kidneys and ideally leave the body via the urethra without pain. Larger stones are painful and may need surgical intervention.

Detailed explanation-2: -Renal stones are formed within the kidneys, and this is called nephrolithiasis. Urolithiasis is a condition that occurs when these stones exit the renal pelvis and move into the remainder of the urinary collecting system, which includes the ureters, bladder, and urethra.

Detailed explanation-3: -Abstract. Urolithiasis (urinary tract calculi or stones) and nephrolithiasis (kidney calculi or stones) are well-documented common occurrences in the general population of the United States. The etiology of this disorder is multifactorial and is strongly related to dietary lifestyle habits or practices.
