Definition

A medical condition where there is an abnormal amount of a specific amino acid in the urine, often leading to kidney stones.

Example

Cystinuria can cause painful kidney stones due to the buildup of cystine in the urine.

Conversation

I read an article about cystinuria and its effects on health.

Really? I haven't heard much about that before.

It's interesting how it's a metabolic defect that can cause kidney stones.

Yeah, I guess understanding cystinuria could help with early diagnosis.

Root Explanation

Cystinuria is formed from "cystis" (from Greek "kystis", meaning bladder or sac) and "-uria" (from Greek "ouron", meaning urine). The term refers to the presence of cystine in the urine, indicating a specific metabolic condition.

Memory Tip

Think of 'cystis' as relating to a 'sac' or 'bladder' where substances are stored, and '-uria' indicating something related to 'urine'. This helps you remember that cystinuria involves cystine being present in the urine.
