Sense: adjective/1
Urinary, renal, and excretory all relate to waste removal from the body, but at different levels. Urinary refers specifically to urine and the organs that handle it — the kidneys, ureters, bladder, and urethra. Renal is narrower, pointing only to the kidneys themselves (renal artery, renal disease). Excretory is the broadest term, covering all ways the body gets rid of waste, including through faeces, sweat, and exhaled carbon dioxide alongside urine. For everyday clinical talk about bladder or urine issues, urinary is the right choice: a urinary tract infection, not a renal or excretory tract infection.

Etymology
Urinary comes from Latin urina (urine) plus the English suffix -ary meaning 'relating to'. The word entered English in the mid-16th century, first used in medical texts to describe anything connected to urine or the organs that process it.
