Kidneys and Bladder

Overview 

Kidney and bladder ultrasound scan is a non-invasive procedure that examines the kidneys and bladder and surrounding structures. This scan helps various conditions affecting the urinary system.  

Why have kidneys and bladder ultrasound scan? 

The most common reason for this ultrasound is pain and this examination may help your doctor determine the cause of that pain. It may be possible to see conditions such as:

  • Kidney stones
  • Bladder stones
  • Fluid in the kidneys (hydronephrosis)
  • Benign conditions such as cysts and small lumps in the kidneys.
  • More serious conditions such as non-benign tumours in the kidneys and bladder.
  • Enlargement of the prostate which may indicate why you are not emptying your bladder.
  • Urinary Retention: Can identify difficulty in emptying the bladder. 

Preparation for the scan 

You will be asked to have a full bladder for this examination. This involves drinking 2 pints of fluid an hour before your appointment time and avoiding urination. We understand this can be uncomfortable and will discuss any concerns you may have when you make your appointment.

How do I get the results? 

After the examination, the Sonographer will explain the findings and go through your report with you. You will receive two copies of the report, one for you and one for your doctor.

Limitations of ultrasound 

Unfortunately, ultrasound has its limitations and we may not get the best views if you have a high BMI, excess gas in your abdomen, or if you haven’t followed the preparation instructions. If we think we can get better views in some of these cases we will rebook you for a follow-up scan, which will be free of charge. 

Ultrasound can only detect abnormalities that are present at the time of the scan. Abnormalities can develop at any time, and while the Sonographer will look for early changes, they cannot predict the future. If you have concerns about anything, please discuss them with the Sonographer before, during or after the scan.
