This page aims to explain the process of active surveillance, which has been recommended as a suitable management option by the Specialist Renal Multidisciplinary Team.

If any questions arise from reading this information, please contact one of the Kidney Cancer Nurse Specialists, their direct line numbers are at the end of this leaflet. 

The kidneys are a pair of organs located at the back of the abdomen which filter blood to remove waste products producing urine. The urine is carried from each kidney to the bladder via a tube called the ureter. When the bladder is full the urine passes out of the body through a tube called the urethra. The urethra opens immediately in front of the vagina in women and at the tip of the penis in men.

What is active surveillance?

After a lesion in a kidney has been identified, usually on a CT scan, the scans are reviewed in the Specialist Renal Multidisciplinary Team Meeting and the specialist team will make recommendations of how best to manage the lesion.

There are several factors which are considered when choosing the right management plan for each patient such as:
•    The patients age and co-morbidities
•    The estimated size of the tumour
•    Your current kidney function

Kidney lesions are typically slow growing and if small, keeping a close eye on them is a safe, non-invasive management option. 

The timing of your CT scans will be determined by one of the consultant urologists. When reviewing the CT scan, we are assessing the size and character of the tumour. If significant changes are reported, then we will re-review your scans in the Specialist Renal Multidisciplinary Team Meeting and discuss any changes to our recommendations with you. 

If the lesion remains stable, most patients stay on active surveillance for up to 3 to 5 years.  

You will be under the care of Frimley Renal Cancer Centre for the duration of your active surveillance, and if you have any concerns, please get in touch with the Renal Cancer CNS.
