Not every kidney stone requires surgical intervention; some people simply need medication and increased fluid intake to pass small stones. More difficult stones may be persistent, large or hard and they may require advanced techniques, such as PCNL surgery(Percutaneous Nephrolithotomy). PCNL is a minimally invasive technique to remove complex or large kidney stones.
Still, PCNL is not a universal solution; specific medical guidelines must be fulfilled to determine eligibility. If you have large kidney stones and are considering PCNL surgery, this blog will give you the necessary information to determine whether you are a candidate and what to expect.
Why PCNL Exists: When Normal Kidney Stone Remedies Just Aren’t Enough
Kidney stones can usually be managed with medications and drinking plenty of water or nonsurgical methods like shock wave therapy. When stones are large, dense or embedded deep within a kidney these nonsurgical methods may be ineffective.
In these cases, PCNL surgery may be a good option as it allows the surgeon to remove the stone through a small back incision using a small camera and other tools.
PCNL is usually only performed when:
Other options have failed
The stone has outgrown ESWL or URS
The stone is causing severe complications like infection, bleeding or blockage of the kidney
As a final note, PCNL is not the first option as it is the stronger and more focused option when other solutions are not quite enough.
The “Ideal Patient” Checklist – Who Truly Needs PCNL Surgery?
You might be a good candidate for PCNL surgery if:
You have a kidney stone bigger than 2 cm
You have multiple stones or a staghorn stone (one that looks like branches and fills the kidney)
You have a stone that is stuck in the lower pole of the kidney
You have had shockwave (ESWL) or laser treatments that have not worked
You have stones that are hard like cystine and calcium oxalate monohydrate
You are obese or have body structures that make other surgeries hard
You have a stone that is causing pain or infections and blood in the urine that are not going away
Your doctor thinks that waiting more could hurt the kidney
If you have 2-3 of the above points, PCNL is usually the best and most safe option.
Who May Not Be a Good Fit for PCNL?
PCNL isn’t a risky procedure; still, there are other options. You may not be a good candidate for a PCNL procedure.
If you:
Pregnant
Have a bleeding disorder that cannot be controlled
Have an active urinary infection that is not treated
Are unfit for anaesthesia
Have a stone that is very small and could be passed naturally or treated with ESWL
Have heart or lung disease that is so severe that it makes surgery risky
If even one of these applies, there are always modifications and other options to be.
Why PCNL May Be the Smarter Choice than Other Stone Removal Methods
Removes large and complex stones in one session
Minimally invasive – only a small cut on the back
Higher success rate with lower recurrence
Better for stones that don’t respond to laser or shockwave
Faster recovery compared to open surgery
Suitable for both adults and elderly patients
PCNL vs Other Kidney Stone Treatments – At a Glance
What Actually Happens During PCNL Surgery?
You get general anaesthesia which means you won’t feel anything.
We will make a very small cut (about 1 cm) in your back.
A special camera will be used to access the kidney directly.
The stone will be broken into smaller pieces with a laser or an ultrasonic tool.
Those pieces will be taken out through the same opening.
A tube or a stent may be left for a short while to drain urine.
The total time for this is 60-90 minutes.
Most patients get to go home after 24-48 hours.
Life After PCNL – Recovery & Returning to Normal Life
Soreness will last for about 3-4 days.
You can start light activities in 3 days and your normal life within 7-10 days.
3+ litres of water will be beneficial and help prevent future stones.
Stent/tube removal will most likely happen in 1-2 weeks.
You will get a follow up ultrasound to make sure your kidneys are clear.
Healthy hydration and simple diet changes will help reduce the chances of your stones coming back by 60-70%.
Possible Risks & Side Effects
Having an expert urologist perform PCNL provides a good opportunity for a successful outcome. However, as with any surgical procedure, there might be a:
Little bit of bleeding
Fever or infection
Leakage of urine for a short time
Possibly having to do a second procedure
That is, most of these problems and risks do not pose a barrier to performing PCNL and are short term.
Conclusion
PCNL means Percutaneous Nephrolithotomy and is one of the best options for large and complicated kidney stones. That being said, this surgery may not be the best for everybody. You would be a good candidate for this surgery if the size of the kidney stone is large, if the stone has been previously treated and the treatments were unsuccessful, or if the large stone is causing dangerous and life-threatening complications.
