About this test
What is an Ultrasound – Kidney & Bladder + Urine Residual Check?
An ultrasound of the kidneys and bladder is a non‑invasive imaging test that uses sound waves to create pictures of the kidneys, ureters, bladder and surrounding tissues. The urine residual check (post‑void residual, PVR) measures the amount of urine left in the bladder after a person has urinated.
Key Parameters Reported
| Parameter | What it shows |
|---|---|
| Kidney size and shape | Detects enlargement, shrinkage or structural abnormalities |
| Presence of cysts, stones or masses | Identifies calculi, tumors or other lesions |
| Kidney echogenicity | Indicates changes in tissue density that may suggest scarring or inflammation |
| Bladder wall thickness | Helps assess bladder dysfunction or obstruction |
| Post‑void residual volume (mL) | Quantifies urine remaining after voiding |
Why is this test done?
- Routine evaluation of kidney health in patients with risk factors (e.g., hypertension, diabetes)
- Investigation of symptoms such as flank pain, hematuria, urinary frequency, urgency or incontinence
- Assessment of bladder emptying in patients with suspected obstruction or neurogenic bladder
- Monitoring of kidney or bladder conditions over time (e.g., after surgery, treatment for stones)
Early Detection
This test can help identify signs of kidney stones, urinary tract obstruction, bladder dysfunction or structural kidney disease, but it does not diagnose a condition on its own. A clinician interprets the images and residual volume together with symptoms, history and other investigations.
What an abnormal result may indicate
- High residual volume: possible bladder outlet obstruction, neurogenic bladder, or impaired detrusor contractility.
- Low residual volume: may be normal or reflect over‑distension of the bladder.
- Kidney cysts or masses: could be benign or malignant; further imaging or biopsy may be required.
- Kidney stones: visible as echogenic foci with acoustic shadowing.
Many factors—hydration status, recent fluid intake, medications (e.g., diuretics, anticholinergics), and recent bladder activity—can influence findings. Therefore, results are considered in clinical context.
Who might be advised to get this test?
- Adults with hypertension or diabetes at risk for kidney disease
- Individuals with urinary symptoms (pain, frequency, urgency, incontinence)
- Patients with a history of kidney stones or bladder disorders
- Those undergoing evaluation for potential bladder outlet obstruction (e.g., benign prostatic hyperplasia in men)
- Patients needing baseline imaging before or after renal or urologic procedures
In short: An ultrasound of the kidneys and bladder with a residual volume check provides a safe, painless snapshot of urinary tract anatomy and function, aiding clinicians in diagnosing and monitoring kidney and bladder conditions.
Preparation_en
Fasting: No fasting is required for this imaging test. If you are also scheduled for a blood test that requires fasting, follow the fasting instructions for the blood test.
Procedure:
- You will lie on an examination table while a gel is applied to your abdomen.
- A handheld transducer (probe) is moved over the area to capture images; the process takes about 15–30 minutes.
- After the scan, you will be asked to urinate in a private area. The volume of urine left in the bladder (post‑void residual) is measured using a small probe or by a second ultrasound.
What to expect:
- The procedure is painless; you may feel a mild pressure from the probe.
- No needles or injections are involved.
Precautions:
- Stay well hydrated before the test; avoid excessive fluid intake immediately before the scan.
- If you are on medications that affect bladder function (e.g., anticholinergics, alpha‑blockers), inform the technician.
- No special restrictions on exercise or alcohol are needed.

Before your test
No special preparation needed. Eat and drink normally unless your doctor says otherwise.
Sample type: Imaging
Report parameter guide
Kidney Size
Overall length and width of each kidney
Low: May indicate chronic kidney disease or atrophy
High: May indicate hydronephrosis, cysts, or acute swelling
Cortical Thickness
Thickness of the outer layer of the kidney
Low: Can indicate chronic kidney disease or scarring
High: Can be normal or slightly increased in acute inflammation
Echogenicity
How bright the kidney tissue appears on ultrasound
Low: May suggest fatty infiltration or low tissue density
High: May indicate scarring, fibrosis, or kidney stones
Presence of Stones
Visible hard deposits within the kidney or ureter
Low: N/A
High: Presence of stones can cause pain, obstruction, or infection
Hydronephrosis
Swelling of the kidney due to urine backup
Low: N/A
High: Can indicate obstruction, stones, or bladder dysfunction
Bladder Wall Thickness
Thickness of the bladder lining
Low: May suggest underactive bladder or low muscle tone
High: Can indicate bladder outlet obstruction, infection, or inflammation
Bladder Capacity
Maximum volume the bladder can hold
Low: May indicate small bladder capacity or neurogenic bladder
High: Can indicate bladder distension or overactivity
Post-void Residual Volume
Amount of urine left in bladder after voiding
Low: Low residual is normal
High: Can indicate bladder outlet obstruction, weak detrusor muscle, or neurological issues
