How to Pronounce Staghorn Calculus

Say it like this: STAG-horn KAL-kyoo-lus. The first part rhymes with 'bag,' the second part sounds like 'horn' (like a horn instrument), and the last part sounds like 'calculus' from math class. The stress (loudest part) falls on STAG in the first word and KAL in the second word.

A stag is a male deer with large, branching antlers. Doctors use this word because the stone's shape resembles those antlers spreading out in multiple directions inside the kidney.

In medicine, 'calculus' (pronounced KAL-kyoo-lus) means a hard stone made of minerals that forms inside the body. It's different from the math calculus you might learn in school—same word, totally different meaning!

The term has five syllables total: stag-horn (2) + cal-cu-lus (3). Breaking it down: STAG / HORN / KAL / KYU / LUS.

People often stress the wrong syllable and say 'stag-HORN' or 'cal-CU-lus' instead of 'STAG-horn' and 'KAL-kyoo-lus.' Remember: the first syllable of each word gets the punch, not the middle or last part.

It's a large kidney stone that branches out like the horns of a stag (male deer), filling different parts of the kidney's system. Think of it as a stone that has multiple arms or branches spreading through the kidney instead of being one small, round stone.

Yes! You'll hear 'renal calculus' (a kidney stone in general), 'gallstone' (a similar stone in the gallbladder), and 'calculi' (the plural form of calculus). All of these use the same root word meaning 'stone.'

Here's an example: 'The radiologist identified a staghorn calculus on the X-ray because of its distinctive branching shape.' This sentence shows how doctors use the term when describing what they see in imaging.
