Silent Signals: Decoding the Language of Anuria in Urology

Anuria is a medical term used in describing the absence or when there is a significant decline in the production of urine. Specifically, it refers to a condition where your urine output is less than 100 milliliters per day. Anuria is often an indication that there is a severe damage or complete stop in your kidney function, which is an important part of your body’s waste elimination system.

Anuria requires immediate medical attention as it is a serious health issue or condition. Treatment aims to address the underlying cause and may involve interventions to restore your kidney function or get rid of the obstruction.


One of the primary symptom of anuria is the significant reduction or the absence of your urine output. Usually, healthcare professionals use the baseline of less than 100 milliliters of urine production per day to diagnose anuria. In addition to this main symptom, you may experience the following when you have anuria:

  • Swelling (edema) — Reduced urine output often leads to fluid retention, that can cause swelling in various parts of your body, such as your legs, ankles, or face.
  • Discomfort or pain — You may experience pain or discomfort in your abdominal or lower back region, especially if there is an underlying cause, such as kidney obstruction or injury.
  • Changes in blood pressure — Anuria can affect your blood pressure levels. You may experience elevated blood pressure, which can contribute to other complications.
  • Nausea and vomiting — The build up of waste products in your body because of reduced urine output can lead to nausea and vomiting.
  • Fatigue and weakness — The inability to effectively eliminate waste from your body can result in a build-up of toxins, leading to feelings of fatigue and weakness.


Anuria can be caused by various factors. Some common causes include:

  • Acute Kidney Injury (AKI) — Sudden and severe kidney damage, often due to conditions like dehydration, severe infections, or certain medications, often lead to anuria.
  • Chronic Kidney Disease (CKD) — Advanced stages of chronic kidney disease, where your kidneys lose their function progressively, may result in anuria.
  • Urinary tract obstruction — Blockages in your urinary tract, such as kidney stones, tumors, or an enlarged prostate in males, can cause obstruction in the normal flow of urine, causing anuria.
  • Severe dehydration — In situations of extreme fluid loss or dehydration, your body conserves water by reducing your urine production, potentially leading to anuria.
  • Hypovolemic shock — Anuria can occur in severe cases of hypovolemic shock, where your body is in a state of low blood volume due to conditions like massive bleeding or trauma.
  • Certain medications — Some medications, especially those that can affect your kidney function, may contribute to anuria. It’s important to monitor and adjust your medications under medical supervision.
  • Infections — Serious infections, particularly those affecting your kidneys, can lead to acute kidney injury and subsequent anuria.
  • Autoimmune diseases — Conditions such as lupus or vasculitis can affect kidney function and contribute to your anuria.
  • Preeclampsia — In pregnant women, preeclampsia, a condition characterized by high blood pressure and organ damage, can lead to a decreased urine output, which can potentially progress to anuria.
  • Severe burns — Extensive and severe burns may cause a reduction in blood flow to your kidneys, leading to kidney injury and anuria.

It’s important to note that anuria is a serious medical condition that requires immediate medical attention. If you suspect anuria or have experienced a sudden decrease in your urine output along with other concerning symptoms, seek immediate medical care to determine the underlying cause and for appropriate treatment or action plan.
