What will happen?
Hospital admission is not a prerogative for the procedure, but as everybody is different, you may need to stay in hospital and the length of hospitalization may vary.
You will arrive in the Interventional Radiology Suite where the interventional radiologist (a doctor specially trained to perform this procedure) and radiographer will explain the procedure and answer your questions. The study usually takes about 60 minutes. After completion, you will be monitored for 2 hours for possible complications.
Do I need any test before the procedure?
You will be asked to have following blood tests:
PI/FIT/Platelets — to assess the risk of post procedural bleeding.
You should discuss any allergy history (particularly to Iodine) with the radiologist prior to booking a nephrostomy.
The nephrostomy procedure
You will have a drip placed in the arm for vascular access. Mild sedation might be required. You will be lying on your stomach and under local anesthesia and sterile conditions, a small incision will be made on your back. The radiologist will use X-rays and ultrasound to insert a needle into your kidney. Contrast (x-ray dye) will be injected and the nephrostomy catheter will be inserted into your kidney.
The catheter will be connected to a drainage bag and the insertion site will be covered with a dressing. The urine in the bag may contain some blood at first; however the blood usually clears with time.
You and/or the member of your family will be instructed about the bag care.
Does it hurt?
You will feel a bee sting when the doctor numbs the skin. You may feel some pressure and discomfort when the tube is inserted. We may need to give you extra medication to help you relax and to reduce your pain.
Some discomfort is to be expected for the first week after the tube insertion.
What are the risks?
Bleeding at the puncture site happens seldom and is usually minimal. In the unlikely case of arterial bleeding, surgical intervention or embolization may be necessary to control it.
Infection can be expected with prolonged procedure. We may need to give you antibiotics to prevent it.
Allergic reaction to X ray contrast is very rare (moderate to serious reactions occur in 1/50.000 — 150.000 people). You should mention any allergy history to the radiologist in order to organize appropriate anti-allergic regime.
When will I get my results?
The radiologist will be able to talk to you after the procedure, but all the relevant details will only be available at your official appointment with referring doctor.
When will I resume my normal activities?
If no complications occur, you will be able to get back to your normal life the next day. You will have to avoid any heavy physical activity while the tube is inserted and to take showe
