Morphology
The phrase is compositionally built from 'renal' (kidney-related) and 'calculus' (a concretion or stone), so its meaning 'stone in the kidney' is directly derivable from the constituents. It is a formal medical term (equivalent to 'kidney stone'), but given the medical senses of both words a B1 learner who knows them would understand the MWE.
Etymology
Renal calculus comes from a simple image: renal means 'of the kidney' and calculus means 'small stone'. So the name literally pictures a 'small stone' in the kidney, which is why it means a hard mass there that can cause pain or block urine.
