Urine is produced in the kidney and flows down a small tube called the ureter into the bladder. Sometimes the flow of urine is blocked due to stones, infection, congenital abnormalities or trauma. To restore the flow, a small catheter (tube) can be placed through the skin of the lower back into the kidney. Urine will then drain into a small bag. A nephrostomy tube may be in place for days, weeks or months.
Using ultrasound, the interventional radiologist will locate the kidney and insert a special hollow needle through the skin into the kidney. Using live X-ray (fluoroscopy) for guidance, the doctor will guide a small catheter into the kidney. The portion of the catheter on the outside of the skin will be connected to a drainage bag. A small stitch (suture) and/or an adhesive clip will hold the catheter in place on the surface of the skin. Your child will be protected by an X-ray shield.
No. We will use either intravenous sedation or general anesthesia so your child isn't awake.
Approximately one hour.
The procedure is considered low-risk. However, potential complications include:
The catheter site may be tender for several days.
We will place gauze and a clear bandage over the catheter site. In addition, the catheter will be secured with a locking device (StatLock®) which must not be removed. The bandage must remain dry and in place at all times. You may sponge-bathe your child, but must keep the site dry.
Your child must avoid activities, such as contact sports or rough playing, which may result in a pull to the catheter and damage to or loss of the catheter.
