Additional Urine Residual / Internal Pelvic Scan in Hisar

What is an Additional Urine Residual / Internal Pelvic Scan?

An Additional Urine Residual (also called a post‑void residual or post‑void residual volume) is a simple imaging test that measures how much urine remains in the bladder after you have finished urinating. The test is usually done with a small ultrasound probe that is placed on the lower abdomen.

What it measures

Why it is done

• To evaluate urinary symptoms such as:
  • Frequent urination
  • Urgency
  • Incomplete bladder emptying
  • Weak urine stream
• To monitor conditions that can cause urinary retention, e.g. prostate enlargement, neurological disorders, or post‑operative recovery.
• To help decide whether medication, catheterisation, or surgery is needed.

Early detection

This test can help identify signs of urinary retention or bladder dysfunction, but it does not diagnose a disease on its own. A doctor interprets the result together with symptoms, history, and other investigations.

What an abnormal result may mean

• High residual volume may indicate bladder outlet obstruction, weak detrusor muscle, or nerve problems.
• Low residual volume is usually normal, but very low values can sometimes be seen in overactive bladder.

Many factors—hydration status, recent fluid intake, certain medications, or recent exercise—can influence the measurement.

Who might be advised to get this test

• Men and women with urinary symptoms.
• Patients with known prostate problems, spinal cord injuries, or after pelvic surgery.
• Individuals being evaluated for possible catheterisation or surgery.

Quick summary

The post‑void residual scan is a quick, non‑invasive ultrasound that measures how much urine remains in the bladder after you finish urinating. It helps doctors understand urinary retention and plan appropriate treatment.

Preparation for the Test

• Fasting – No fasting is required for a post‑void residual scan.
• If you are also scheduled for a fasting blood test – follow the fasting instructions for the blood test; otherwise, just stay hydrated.
• Procedure – You will be asked to empty your bladder fully, then lie on your back while a small ultrasound probe is placed on the lower abdomen. The scan takes about 5–10 minutes.
• What to expect – The procedure is painless. You may feel a slight pressure from the probe, but no needles or injections are involved.
• Precautions – Avoid heavy exercise or alcohol 24 h before the test if you are also doing other tests that require it. Continue any prescribed medications as usual unless your doctor advises otherwise.
• Final note – Confirm the exact preparation details with your doctor or the lab. This information is general educational material and not a substitute for professional medical advice.
