Percutaneous Stone Removal

What is percutaneous stone removal?

This is a surgical procedure in which stone material is removed directly from a patient’s kidney. In this procedure, the surgeon makes a small incision in the patient’s back and then inserts a scope through the incision directly into the kidney. Through this scope, a multitude of instruments can be used to fragment the kidney stone and then remove the stone material.

What is the purpose of percutaneous stone removal?

This surgery is generally reserved for patients who develop large or complex kidney stones that cannot be effectively removed with less invasive techniques. This treatment decision is most often reflected by total stone size, but can also be determined by the composition of the stone material, as well as patient factors such as overall health and obesity.

This procedure is performed in the operating room with the patient under general anesthesia. There are two stages in the procedure. The first stage involves placing a needle and then a wire through the skin into the kidney. This is performed with the help of x-ray equipment and thus may be performed in the hospital radiology department or at times in the operating room. The second step of the procedure is placement of a scope over the wire into the kidney to subsequently break apart stone material and remove it.

Following the surgery, the patient generally has a drainage tube that is placed through the flank region into the kidney, as well as a catheter inserted through the urethra into the bladder. Patients typically stay in the hospital between 2 to 7 days after this surgery.

What are common symptoms following my percutaneous stone removal?

The most commonly reported symptom following this procedure is pain at the incision site. Even though a small incision is used in this procedure, the flank area is very sensitive and may exhibit discomfort for several days following the surgery. By the time you leave the hospital, however, you will be comfortable with the help of oral pain medication.

Blood in the urine is also very common following the surgery and may intermittently occur for several weeks following the surgery.

When should I contact my physician?

You should contact your physician any time that you develop a persistent fever greater than 101 degrees Fahrenheit. Additionally, you should contact your physician if you develop severe flank pain or abdominal pain that is not improved with the pain medication that you are given. If you develop significant blood in the urine, then you should also contact your physician. This would be denoted by passage of urine that is the consistency of ketchup or associated with clots greater than silver dollar size.
