Percutaneous Nephrolithotomy (PCNL) is done to remove large (greater than 2 cm) kidney stones or staghorn stones through the skin. The doctor makes a small incision in your back. A thin wire is placed through the incision and goes into the kidney and down the ureter (urine tube that goes from the kidney to your bladder). An X-ray helps your doctor guide the wire. A tube is then passed into the kidney to make a larger tract. A viewing scope is put into the kidney. The stone is broken into pieces with sound waves and taken out.
A small hollow tube (nephrostomy tube) is left in the tract for 12 – 36 hours. Sometimes the doctor needs to remove more stones during a “second look.” You will be in the hospital 1-4 days. Most people go home with no tubes in place.
In rare cases, you may have bleeding and need a blood transfusion. There is also a rare chance you could get a lung injury, causing a collapsed lung. This prevents your lung from expanding properly when you try to breathe in, causing shortness of breath and chest pain.
You may leak urine from the wound for 2-3 days. It is normal for the drainage to be slightly bloody or pink in color.
You may need gauze on the site for a few days. Keep it on for 24 hours. Remove it before taking a shower. Replace as needed.
If you have a stent (a tube from the kidney to the bladder to keep the urine flowing) you may:
Have burning when you pass urine.
Have a strong urge to pass urine.
Pass urine more often.
The stent may be taken out at your follow-up clinic visit. Passing blood in your urine is common. This will clear up by drinking 8-10 (8 oz.) glasses of fluid each day.
Eat a balanced diet. Drink at least 8-10 (8 oz) glasses of fluid daily. If you get up several times at night to pass urine, you may want to decrease your fluid intake after dinner.
You may shower.
Nothing strenuous until it is ok’d by your doctor. Climbing stairs and walking are okay.
No intercourse for 1 week.
Do not drive for 1 week or while taking narcotic pain medicine.
Do not lift more than 10 pounds for the first 2 weeks.
Your doctor will let you know when you can go back to work. You may need to be off for 2 weeks.
If antibiotics are ordered be sure to take them all. Pain pills will be ordered. Your pharmacist will instruct you on how to take them.
