Which of the following describes the presence of several large kidney stones?

Nephrolithiasis refers specifically to the condition of having kidney stones, which are hard deposits made of minerals and salts that form inside the kidneys. The term "nephro" relates to the kidneys, and "lithiasis" denotes the presence of stones. When multiple large kidney stones are present, it is explicitly classified under nephrolithiasis, making it the most accurate choice.

In contrast, nephrocele refers to a pathological dilation of the kidney, while glomerulonephritis is an inflammation of the kidney's filtering units, the glomeruli. Nephrectomy involves the surgical removal of a kidney and does not pertain to the presence of kidney stones. Thus, nephrolithiasis is the correct term to denote the presence of several large kidney stones and accurately describes the condition in question.
