How to talk about urinating in Japanese, from polite to casual, including child-friendly terms and medical/formal expressions.

The most common, neutral way to say 'pee' for both children and adults in daily conversation. Literally 'do pee'.

I'm going to go pee real quick.

Literally 'do small convenience'. More direct and slightly crude; used mainly by men or in rough speech. Can be vulgar depending on context.

Child-friendly and everyday word for urine. Can be used by adults in casual settings.

I feel like I need to pee. (lit. 'Pee seems about to come out.')
赤ちゃんのおしっこを検査に出した。
I took the baby's urine for testing.
Formal/medical term for urine. Used in compounds like 尿検査 (urinalysis).
尿に血が混じっている。
There is blood in the urine.
Crude term for urine, similar to 'piss'. Avoid in polite conversation.
Expressing the physical need to go to the bathroom.
Polite and natural way to say 'I want to go pee'. Suitable for most situations.
すみません、おしっこに行きたいです。
Excuse me, I need to go to the bathroom (to pee).
More indirect; just says 'I want to go to the toilet', which implies urination in context. More polite in formal settings.
会議中ですが、トイレに行きたいです。
I'm in a meeting, but I need to use the restroom.
Very polite, euphemistic way to say you need to use the restroom. Often used by women or in formal situations.
お手洗いに行きたいのですが。
I would like to use the restroom.
Words used with or by small children, or in very casual, cute contexts.
Onomatopoeic word for pee, used in baby talk or when talking to toddlers. Often used as a verb with する.
しーしーする？
Do you need to pee? (to a child)
Another baby-talk word for pee, similar to 'wee-wee'. Used with small children.
ちっち出た？
Did you pee? (to a toddler)
Very informal, often crude ways to refer to urination.
Slang for pee/piss, derived from 小便. Considered vulgar and childish.
ション便たれてんじゃねーよ。
Don't piss yourself! (very rough)
English uses 'pee' as a verb directly ('I need to pee'), but Japanese usually requires a noun + する construction (おしっこをする) or a phrase like トイレに行く. Saying ピーする is not natural Japanese.
Women and men in polite company often use お手洗い (restroom) rather than direct words for urination. 小便 is particularly masculine and can be crude.
小便が臭い。
The piss stinks.
