Percutaneous kidney procedures

Definition

Percutaneous (through the skin) urinary procedures help drain urine from your kidney and get rid of .

Description

A percutaneous nephrostomy is the placement of a small, flexible tube () through your skin into your kidney to drain your urine. It is inserted through your back or flank.

Percutaneous nephrostolithotomy (or nephrolithotomy) is the passing of a special medical instrument through your skin into your kidney. This is done to remove kidney stones.

Most kidney stones pass out of the body on their own through urine. When they do not, your health care provider may recommend these procedures.

During the procedure, you will lie on your stomach on a table. You will be given a shot of lidocaine. This is the same medicine your dentist uses to numb your mouth. The provider may give you medicines to help you relax and reduce pain.

If you have nephrostomy only:

  • The surgeon inserts a needle into your skin. Then the nephrostomy catheter is passed through the needle into your kidney.
  • You may feel pressure and discomfort when the catheter is inserted.
  • A special type of is used to make sure the catheter is in the right place.

    • If you have percutaneous nephrostolithotomy (or nephrolithotomy):

  • You will receive general anesthesia so that you will be asleep and feel no pain.
  • The surgeon makes a small cut (incision) on your back. A needle is passed through the skin into your kidney. Then the tract is dilated and a plastic sheath is left in place allowing a tract to pass instruments.
  • These special instruments are then passed through the sheath. Your surgeon uses these to take out the stone or break it into pieces.
  • After the procedure, a tube is placed in the kidney (nephrostomy tube). Another tube, called a stent, is placed in the ureter to drain urine from your kidney. This allows your kidney to heal.

    • The place where the nephrostomy catheter was inserted is covered with a dressing. The catheter is connected to a drainage bag.

    Why the Procedure Is Performed

    Reasons to have a percutaneous nephrostomy or nephrostolithotomy are:

  • Your flow of urine is blocked.
  • You are having a lot of pain, even after being treated for a kidney stone.
  • X-rays show the kidney stone is too large to pass by itself or to be treated by going through the bladder to the kidney.
  • Urine is leaking inside your body.
  • The kidney stone is causing .
  • The kidney stone is damaging your kidney.
  • Infected urine needs to be drained from the kidney.

    • Risks

    Percutaneous nephrostomy and nephrostolithotomy are generally safe. Ask your surgeon about these possible complications:

  • Pieces of stone left in your body (you may need more treatments)
  • Bleeding around your kidney
  • Problems with kidney function, or kidney(s) that stop working
  • Pieces of the stone blocking urine flow from your kidney, which may cause very bad pain or kidney damage
  • Kidney infection

    • Before the Procedure

    Tell your surgeon:

  • If you are or could be pregnant.
  • What medicines you are taking. These include medicines, supplements, or herbs you bought without a prescription.
  • If you have been drinking a lot of alcohol.
  • You are allergic to contrast dye used during x-rays.

    • On the day of the surgery:

  • You may be asked not to drink or eat anything for at least 6 hours before the procedure.
  • Take the medicines you have been told to take with a small sip of water.
  • You will be told when to arrive at the hospital. Be sure to arrive on time.

    • After the Procedure

    You are taken to the recovery room. You may be able to eat soon if you do not have an upset stomach.

    You may be able to go home within 24 hours. If there are problems, your doctor may keep you in the hospital longer.

    The surgeon will take out the tubes if x-rays show that the kidney stones are gone and your kidney has healed. If stones are still there, you may have the same procedure again soon.

    Outlook (Prognosis)

    Percutaneous nephrostolithotomy or nephrolithotomy almost always helps ease the symptoms of kidney stones. Often, the surgeon is able to remove your kidney stones completely. You sometimes you need to have other procedures to get rid of the stones.

    Most people who are treated for kidney stones need to make lifestyle changes so that their bodies do not make new kidney stones. These changes include avoiding certain foods and not taking certain vitamins. Some people also have to take medicines to keep new stones from forming.
