IPA: /ˌæn.jʊˈriː.sɪs/
KK: /ænjuˈrisɪs/
A medical condition where a person is unable to urinate.
The doctor diagnosed her with anuresis after she reported not being able to urinate for several hours.
Anuresis is formed from "a-" (meaning without) and "nuresis" (from Greek "ouron" meaning urine and "esis" meaning action or process). The word describes the condition of being without the ability to urinate, hence the absence of urination.
Think of 'a-' meaning without, and 'nuresis' relating to the action of urination. This helps you remember that anuresis refers to the inability to urinate.
