Kidney stones, tiny calcified deposits that form in the kidneys, can cause excruciating pain and significant discomfort. Affecting approximately 1 in 10 individuals in their lifetime, these stones often require medical intervention to prevent complications and alleviate symptoms. While some small stones may pass naturally, larger or more stubborn stones necessitate procedures like Ureteroscopy (URS) or Percutaneous Nephrolithotomy (PCNL).
Deciding between URS and PCNL depends largely on the size, location, and composition of the kidney stone, as well as the patient's overall health. At Manipal Hospitals, our urologists in Delhi specialise in a range of advanced treatments, guiding patients through these critical choices with expertise and empathy. Let's delve into these two primary treatment options to help you understand which might be right for your specific situation.

Understanding Kidney Stones
Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They can develop when your urine contains more crystal-forming substances – such as calcium, oxalate, and uric acid – than the fluid in your urine can dilute. Simultaneously, your urine might lack substances that prevent crystals from sticking together, creating an ideal environment for stone formation.
What are Kidney Stones?
These stones can vary in size from as small as a grain of sand to as large as a pearl, or even bigger in some cases. They typically form in the kidney and can then travel down the urinary tract. The excruciating pain often begins when a stone blocks the flow of urine, causing pressure buildup.
Common Symptoms
Recognising the symptoms of kidney stones is crucial for timely diagnosis and treatment. Common signs include:
-
Severe pain: Often felt in the side and back, below the ribs, radiating to the lower abdomen and groin. This pain can come in waves.
-
Painful urination: Known as dysuria.
-
Pink, red, or brown urine: Indicating blood in the urine (hematuria).
-
Cloudy or foul-smelling urine: May signal an infection.
-
Nausea and vomiting often accompany intense pain.
-
Frequent urge to urinate: Even if only a small amount is passed.
-
Fever and chills: If an infection is present.
Ureteroscopy (URS): A Closer Look
Ureteroscopy is a minimally invasive procedure widely used for removing kidney and ureteral stones. It's particularly effective for stones located in the ureter (the tube connecting the kidney to the bladder) or in the kidney itself, typically those of small to medium size.
What is a Ureteroscopy Procedure?
During a Ureteroscopy procedure, a thin, flexible or rigid telescope-like instrument called a ureteroscope is inserted through the urethra and bladder, up into the ureter and kidney. This allows the urologist to visualise the stone directly. The procedure is performed under general anaesthesia.
When is URS Recommended?
Ureteroscopy for kidney stones is often the preferred choice for:
-
Stones located in the ureter.
-
Kidney stones typically smaller than 2 cm.
-
Patients who cannot undergo extracorporeal shock wave lithotripsy (ESWL) due to various medical reasons.
-
Patients on blood thinners, as URS generally has a lower risk of bleeding compared to other procedures.
The Ureteroscopy with Laser Lithotripsy Process
Once the stone is located, the urologist uses advanced techniques, most commonly Ureteroscopy with laser lithotripsy. A laser fibre is passed through the ureteroscope to break the stone into smaller, passable fragments. These fragments are then either retrieved using a small basket or left to pass naturally. In many cases, a temporary stent is placed in the ureter to ensure proper drainage and prevent swelling, which is usually removed a few days or weeks later. This procedure boasts high success rates, with studies showing over 90% stone-free rates for stones up to 1.5 cm.
Ureteroscopy Cost & Recovery
The Ureteroscopy cost can vary depending on factors such as the complexity of the stone, the hospital chosen, and the need for additional procedures like stent placement. It is generally considered a cost-effective treatment.
Ureteroscopy recovery is typically swift. Most patients can go home the same day and resume normal activities within a few days. You might experience some discomfort, frequent urination, or blood in the urine due to the stent, but these usually subside quickly.
Is Ureteroscopy Painful?
Patients often ask, "Is Ureteroscopy painful?" The procedure itself is performed under general anaesthesia, so you won't feel any pain during the operation. Post-procedure, some discomfort, urgency, or mild pain in the back or side is common, especially if a stent is placed. Pain medication can effectively manage this, and most patients report that it is manageable and far less severe than the pain caused by the stone itself.
Percutaneous Nephrolithotomy (PCNL): When It's Needed
When kidney stones are large or complex, Percutaneous Nephrolithotomy (PCNL) often becomes the gold standard treatment. This procedure is more invasive than URS but highly effective for removing significant stone burdens.
What is the PCNL Procedure?
The PCNL Procedure involves making a small incision (typically less than 1 cm) in the back or flank. Through this incision, a guidewire is advanced into the kidney, creating a tract. A nephroscope (a specialised endoscope) is then inserted directly into the kidney to visualise and remove the stone. Ultrasonic or laser devices are used to break large stones into fragments that can be suctioned out. This direct approach allows for the removal of larger stones in a single session.
When is PCNL Recommended?
PCNL is primarily recommended for:
-
Large kidney stones (typically greater than 2 cm).
-
Staghorn calculi, which are complex stones that fill a significant portion of the kidney's collecting system.
-
Stones that have not responded to other treatments like ESWL or URS.
-
Stones in challenging locations within the kidney.
PCNL Success Rates & Recovery
PCNL boasts impressive success rates, often achieving stone-free rates of up to 98% for large or complex stones, making it incredibly effective for difficult cases. PCNL recovery typically requires a slightly longer hospital stay (1-3 days) compared to URS. Patients may experience some flank pain and blood in the urine initially. Most individuals can return to light activities within a week and full activity within 2-4 weeks. Our team of experienced urologists in Delhi ensures comprehensive post-operative care to facilitate a smooth recovery.
Ureteroscopy vs. PCNL: Making the Right Choice
Choosing between Ureteroscopy vs PCNL is a critical decision that should always be made in consultation with a qualified urologist. Both procedures are highly effective, but their indications differ significantly.
Key Factors in Decision Making
The primary considerations include:
-
Stone Size and Location: This is the most crucial factor.
-
Stone Hardness: Some stones are very dense and harder to fragment.
-
Patient's Anatomy: Variations in kidney and ureter anatomy can influence the choice.
-
Medical History: Pre-existing conditions, especially those affecting bleeding or anaesthesia.
-
Patient Preference: Discussing recovery times, invasiveness, and potential risks.
Stone Size and Location
For stones generally smaller than 2 cm, especially those in the ureter, Ureteroscopy is often the preferred and less invasive option. It offers quicker recovery and less discomfort. For larger kidney stones (over 2 cm) or complex stones like staghorn calculi, PCNL provides a much higher chance of complete stone removal in a single session, significantly reducing the likelihood of residual fragments and future complications. At Manipal Hospitals, our dedicated team, including our urologists in Delhi, utilises state-of-the-art diagnostic tools to precisely evaluate your stone characteristics and recommend the most appropriate procedure.

FAQ's
Most patients can return home the same day or the next, with full recovery and return to normal activities typically within a few days to a week. If a stent is placed, some discomfort may persist until its removal.
PCNL has a very high success rate, often achieving stone-free rates of up to 98% for large or complex kidney stones, making it highly effective for challenging cases.
Yes, unfortunately, kidney stones can recur. The procedures remove existing stones but don't prevent new ones from forming. Lifestyle changes, dietary modifications, and sometimes medication are crucial for prevention.
The best way is to consult with a urologist. They will evaluate your stone's size, location, and composition, along with your medical history, to recommend the most suitable treatment plan.
Yes, it is one of the most common and effective methods for treating kidney and ureteral stones due to its minimally invasive nature and high success rates.
