Radiology - Nephrostogram

Introduction

This leaflet tells you about having a procedure known as a Nephrostogram. It will explain how the test is carried out and what the possible risks are.

It is not meant as a substitute for an informed discussion between you and your doctor. If you have any questions, please do not hesitate to speak to the doctor caring for you.

What is a Nephrostogram?

You will have previously had a procedure called a nephrostomy. This includes inserting a tube into either one or both of your kidneys. This procedure will be done to check that these tubes are still working by inserting iodinated contrast (x-ray dye) into the tubes and there is no problem with your kidneys or ureters (the tubes from your kidneys to your bladder).

Who has made the decision?

The consultant looking after you and a radiologist will have decided that this test would be appropriate for you to have. However, you will have the opportunity for your opinion to be considered. If after a discussion with the doctor looking after your case, you may decide against the procedure.

Who will be doing the procedure?

A Radiologist or Advanced Practitioner Radiographer will be undertaking your test. They have both had specialist training in using the x-ray equipment and interpreting the images they produce.

Where will the procedure take place?

The procedure will generally take place within the x-ray department, in a designated “screening” room. These rooms are adapted for specialised procedures.

What preparation is required?

There is no specific preparation before you come for your test. You can eat and drink as normal. You may continue to take your regular medications as normal.

If you have any allergies, you must let your doctor know. If you have previously had an allergic reaction to the iodinated contrast (x-ray dye) that is used for CT scans you must make your doctor aware.

Please bring a spare drainage bag with you.

What does the procedure involve?

When you first arrive at the department you will be introduced to the team looking after you during your procedure. If you have any questions, you will be able to have a discussion with the radiologist or radiographer who will be carrying out the nephrostogram. The radiologist/radiographer will then confirm that you have given your consent for the procedure, and you are happy to proceed. If possible, you will then lay on your front (or side) on the x-ray table. A member of the nursing team will then remove the drainage bag. The radiologist/radiographer will then clean the tube before injecting some iodinated contrast. Some images of your kidney and ureters will be taking to make sure that tubes are draining correctly. At the end a drainage bag will be re-attached.

Will it hurt?

It should not be a painful procedure, but you may get some discomfort when the x-ray dye is injected into your kidney, especially if your ureter is blocked.

How long will it take?

There is no exact procedure time, the procedure normally takes between 10 to 20 minutes. As a guide, you should expect to be in the department for about 40 minutes altogether.

Are there any risks or complications with a Nephrostogram?

A nephrostogram is a very safe procedure and complications are a very rare occurrence. The associated risks include an allergic reaction to the iodinated contrast, but this is extremely rare.

Other risks or complications include infection and pain, but these will be discussed with you by the radiologist/radiographer carrying out the procedure when you attend.

What are the benefits of a nephrostogram?

It provides diagnosis of abnormalities of your kidney and ureters and check your tubes. The results of this test will help your doctor to plan the best treatment for your condition.

Are there any alternatives?

Unfortunately, there are no alternative procedures.

Aftercare Advice

Following on from the test, you will be able to continue as normal with your everyday normal activities, including being able to drive straight after your procedure and going back to work.

How do I get the results?

The radiologist performing the nephrostogram may be able to let you know the results before you leave the department, if not the results will be available from the doctor looking after you shortly after.

What if I decide not to have the nephrostogram?

If you attend for your appointment and after a discussion with the radiologist/radiographer you decide against having the test, then we will write to your referring doctor. They will then discuss your options for further treatment with you, at your next appointment in clinic.

Could you be pregnant?

If there is any chance you could be pregnant, please call 0161 206 5091 if your appointment is at Salford Royal Hospital or call 0161 656 1178 if your appointment is at Royal Oldham Hospital.

Is x-ray guidance dangerous?

All x-ray machines use potentially harmful x-rays. Modern equipment is designed to keep the dose you receive as low as possible. If your doctor has asked for this test, they will have decided that the benefits from the procedure outweigh the risks from the very small dose of radiation that you receive.

What if I cannot attend my appointment?

If you have any queries about your appointment or cannot attend, then please telephone the Interventional Radiology department on 0161 206 5091if your appointment is at Salford Royal Hospital or 0161 656 1178 if your appointment is at Royal Oldham Hospital.
