What are the other Names for the Procedure?
- Extracorporeal Shock Wave Lithotripsy
- Percutaneous Nephrolithotomy (PCNL)
- Ureterolithotomy (URS)
What is Kidney Stone Removal surgical procedure?
Kidney Stone Removal is a surgical procedure that involves the removal of kidney stones from one of the ureter tubes (the tubes that carry urine from the kidneys to the bladder), or from the kidney itself.
What part of the Body does the Procedure involve?
A Kidney Stone Removal procedure involves a kidney and/or the ureter.
Why is the Kidney Stone Removal surgical procedure Performed?
A Kidney Stone Removal procedure is generally performed to restore proper urine flow, from within the ureter (urinary retention).
What are some Alternative Choices for the Procedure?
- The physician may take a conservative approach to treatment in certain cases, instead of a Kidney Stone Removal surgery
- This involves hydration, watchful waiting, and the use of medication, if there is a possibility that the stone may get flushed-out spontaneously
What are the Recent Advances in the Procedure?
- Kidney Stone Removal surgical procedures may be performed using minimally invasive techniques
- Mini-Percutaneous Nephrolithotomy procedure is performed using a smaller nephroscope
What is the Cost of performing the Kidney Stone Removal surgical procedure?
The cost of Kidney Stone Removal surgical procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to the Procedure?
- It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding Kidney Stone Removal surgical procedure and what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
- Also, if the procedure involves multiple surgeries or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Kidney Stone Removal surgical procedure:
How is the Kidney Stone Removal surgical procedure Performed?
The type of Kidney Stone Removal procedure to be used depends upon factors, such as:
- Location of the stone within the urinary tract
- Size of the stone
- Composition of the stone
- Presence of other medical co-morbidities
The kidney stones may be removed through any one of the following methods:
Percutaneous Nephrolithotomy (PCNL) procedure:
- This procedure is performed for large stones located within the kidney itself
- The surgery is done under general anesthesia. The surgeon makes a skin incision on the flank region, overlying the kidney
- A wire is introduced through this small incision into the kidney up to the ureter. By using instruments that stretch the surrounding tissue (called dilators); the surgeon creates a space (a “track”) around this wire
- An instrument, called the nephroscope, is then introduced through this track. This helps the surgeon visualize the stones directly
- The stones are then removed using special instruments. A large stone may be broken up, before it is removed
- A tube is then left in place to drain fluid from the surgical site for a period of time and the incision closed
Ureteroscopy (URS) procedure:
- This procedure can be used for stones in the ureter (or even in the kidney) and is performed under general anesthesia
- An instrument, called the ureteroscope, is introduced through the urethra (the distant most portion of the urinary tract, through which urine is voided), guided up the bladder and the ureter
- The stones are visualized directly and removed
Shock Wave Lithotripsy:
- This procedure is performed under sedation using a machine, called a lithotripter
- The lithotripter produces ultrasound waves that are transmitted through the skin and body
- These ultrasound waves break-up the stones into smaller pieces
- Multiple sessions may be required with this procedure
- A Nephrolithotomy (stone removal from the kidney) or Ureterolithotomy (stone removal from the ureter) may be performed using a large skin incision, to expose the kidney or ureter
- The surgeon then enters the affected part of the kidney/ureter, to remove the stone
Where is the Procedure Performed?
- The Kidney Stone Removal procedure is performed in a hospital
- The Shock Wave Lithotripsy procedure may be however, performed on an outpatient basis
Who Performs the Procedure?
An urologist performs a Kidney Stone Removal procedure.
How long will the Procedure take?
The length of the Kidney Stone Removal procedure will depend on the type of chosen technique, for stone removal. It may last from anywhere between a few minutes to a few hours.
What do you need to tell your Physician before the Procedure?
It is very important to provide the following information to your healthcare provider. This enables your healthcare provider in assessing the risks for the Kidney Stone Removal surgical procedure and helps avoid unnecessary complications.
- Provide a complete list of medications you are currently, taking to your physician. This information is useful for a variety of reasons. For example, it can help your healthcare provider prevent complications due to a drug interaction
- If you are allergic to any specific medication or food items
- If you are taking blood thinners, such as aspirin, warfarin, herbal supplements, or any other such medications
- If you or your family members, have a history of bleeding disorders, or if there is a tendency to bleed more than normal
- If you have diabetes, high blood pressure, chest pains, or have previously suffered from a heart attack
- If you have ever been diagnosed with blood clots in your leg (deep vein thrombosis) or lung (embolism of lung)
- If you have a history of frequent bone fractures (this may affect bone-healing, if bones are involved as part of your procedure)
- A list of all previous surgical procedures you have undergone, like for example: Removal of appendix, gallbladder, or any other part, of your body; surgical repair of any body part, such as hernia repair, perforation of bowel wall, etc.
What Preparations are needed, prior to the Procedure?
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient including information related to the medications that are being currently taken
- Some medications increase a person’s chances of bleeding and it may be recommended to discontinue them for a period of time, before the procedure is performed
- Blood tests may be performed to determine if there is a bleeding tendency or any other medical conditions that prevents the person from undergoing the procedure
- Normally local anesthesia is not used; however do inform the physician if you are allergic to any local anesthetics, lidocaine, etc
- Avoid application of any cosmetics, deodorant, or topical medicines on the area, prior to the procedure
- It is advisable to quit smoking and the use of any nicotine based products, for a while, before the surgery
- Consumption of alcoholic drinks must also be avoided for a period of time, as instructed
- The patient must avoid eating or drinking at least 8 hours prior to the surgical procedure, depending on when the procedure is arranged
- For persons suffering from diabetes, it is important that the blood sugar stays within the normal range; if not their diabetologist may have to control blood sugar by recommending insulin and/or a combination of oral medicines
What is the Consent Process before the Procedure?
A physician will request your consent for Kidney Stone Removal procedure using an Informed Consent Form.
Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied by the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
