尚需 is an adverbial phrase meaning 'still needs' or 'still requires'. It combines 尚 (shàng), meaning 'still', 'yet', or 'as yet', and 需 (xū), meaning 'to need' or 'to require'. Together, they express that something remains necessary — often in formal, written, or professional contexts such as medical reports, technical documents, or official announcements. The phrase conveys a sense of incompleteness or pending necessity, implying the action or condition has not yet been fulfilled.

This expression is more formal and concise than alternatives like 还需要 (hái xūyào) and is rarely used in casual spoken Chinese. It frequently appears with verbs indicating actions (e.g., 检查, 治疗, 确认) or abstract nouns (e.g., 观察, 审核). Because it's compact and impersonal, 尚需 is common in academic, administrative, and healthcare settings where objectivity and brevity are valued.
