What does anuric mean?
Anuric is a technical medical adjective describing the state of producing little or no urine. It applies both to patients who are unable to pass urine and to the clinical phases or conditions characterised by that failure, most notably acute kidney injury and end-stage renal disease, where the term appears frequently in phrases such as "anuric phase" or "anuric patient". The word derives from the Greek prefix an-, meaning "without", combined with ouron, meaning "urine", the same root that gives us urology and diuretic. Because complete absence of urine output signals serious renal compromise, anuric carries an inherently grave connotation and is treated as an urgent clinical finding rather than a neutral description. The word belongs firmly to formal medical registers, appearing in hospital charts, nephrology literature, and specialist discussion rather than everyday language, but it is a precise and valuable term for describing one of the most critical indicators of kidney function.
adjectiveRelating to or affected by anuria — the complete or near-complete failure of the kidneys to produce urine.
- Of a patient or kidneys: producing little or no urine, as in anuric renal failure.
"The patient became anuric after the severe dehydration left her kidneys unable to produce urine."
"The nephrologist noted that the patient had been anuric for over twelve hours."
"During the anuric phase of acute kidney injury, dialysis may become necessary."
In medicine, 'anuric' signals one of the kidney's most alarming failures — producing no urine at all — and it comes straight from the Greek word for urine, 'ouron'.

Etymology of anuric
The word anuric comes from the Greek prefix an-, indicating absence, joined to ouron, the Greek word for urine, via the combining form seen in medical vocabulary such as urology and enuresis. It entered English medical usage alongside its parent noun anuria, which denotes the condition of failing to produce urine. Its closest relatives are other terms built on the same Greek root, including diuretic, enuresis, and urology.
