Introduction
Ureteroscopy & PCNL Training in India is one of the most important fellowship programs for urologists who want to master minimally invasive kidney stone surgery. This comprehensive guide explains how to gain practical experience in URS, RIRS, and PCNL through structured hands-on training.As the incidence of kidney stone disease continues to increase globally, especially in India due to changing lifestyles, dehydration, dietary habits, obesity, and metabolic disorders, there is an ever-growing demand for highly skilled urologists capable of performing advanced endourological procedures with precision and confidence.
However, becoming proficient in URS and PCNL is not simply a matter of reading textbooks or attending conferences. These are technically demanding procedures that require exceptional hand-eye coordination, anatomical understanding, fluoroscopic guidance, endoscopic navigation, and the ability to manage intraoperative challenges. These competencies can only be developed through structured, supervised, hands-on surgical training.
Whether you are a resident in urology, a practicing consultant, or an international surgeon seeking advanced skills, a dedicated hands-on training program can significantly enhance your surgical confidence and improve patient outcomes.
This comprehensive guide explores everything you need to know about Ureteroscopy and PCNL training in India, including the procedures, required skills, learning pathways, training methods, career opportunities, and how to choose the right fellowship program.
The Rising Burden of Kidney Stone Disease
Kidney stone disease has become one of the most common urological conditions worldwide. According to various epidemiological studies, the prevalence of urolithiasis has steadily increased over the last few decades, affecting millions of people every year.
India, particularly the northern and western regions, lies within the so-called “Stone Belt,” where climatic conditions, dietary patterns, and limited water intake contribute to a higher incidence of urinary stones.
Common factors contributing to stone formation include:
- Inadequate hydration
- High salt consumption
- Diets rich in animal protein
- Obesity
- Diabetes and metabolic syndrome
- Hyperparathyroidism
- Recurrent urinary tract infections
- Genetic predisposition
- Sedentary lifestyles
Because kidney stones have a high recurrence rate, many patients require repeated interventions during their lifetime. This creates a continuous need for skilled endourologists who can provide safe, effective, and minimally invasive treatment.
Evolution of Kidney Stone Surgery
A few decades ago, the treatment of large kidney stones relied heavily on open surgery. While effective, open procedures were associated with significant postoperative pain, larger scars, longer hospital stays, increased blood loss, and delayed return to normal activities.
The introduction of minimally invasive endourological techniques transformed stone management. Today, most kidney and ureteric stones can be treated using advanced endoscopic procedures such as:
- Ureteroscopy (URS)
- Flexible Ureteroscopy (FURS)
- Retrograde Intrarenal Surgery (RIRS)
- Percutaneous Nephrolithotomy (PCNL)
- Mini-PCNL
- Micro-PCNL
- Extracorporeal Shock Wave Lithotripsy (ESWL) for selected cases
These techniques have dramatically improved patient outcomes by reducing surgical trauma while maintaining high stone-free rates.
What is Ureteroscopy (URS)?
Ureteroscopy is a minimally invasive endoscopic procedure used to diagnose and treat stones and other conditions affecting the ureter and kidney.
During the procedure, a thin, specialized instrument known as a ureteroscope is inserted through the natural urinary tract—passing through the urethra, bladder, and ureter—without any external incision.
The surgeon visualizes the urinary tract using a high-definition camera and treats the stone using laser energy or retrieval devices.
Modern ureteroscopes are highly sophisticated and provide excellent visualization even within the smallest calyces of the kidney.
Types of Ureteroscopy
Semi-Rigid Ureteroscopy
Semi-rigid ureteroscopes are commonly used for:
- Lower ureteric stones
- Mid-ureteric stones
- Diagnostic ureteroscopy
- Ureteric strictures
- Stent removal
These instruments provide excellent durability and are relatively easy to maneuver in the lower urinary tract.
Flexible Ureteroscopy (FURS)
Flexible ureteroscopes have revolutionized modern endourology.
Their ability to actively deflect allows surgeons to reach almost every calyx of the kidney.
Flexible ureteroscopy is widely used for:
- Renal calculi
- Upper ureteric stones
- Lower pole stones
- Multiple renal stones
- Difficult anatomical situations
Digital flexible ureteroscopes now provide exceptional image quality and enhanced maneuverability, making them indispensable in advanced stone surgery.
What is RIRS (Retrograde Intrarenal Surgery)?
RIRS is an advanced form of flexible ureteroscopy used to treat kidney stones entirely through the natural urinary tract.
Unlike PCNL, RIRS does not require a skin incision or renal puncture.
Using a flexible ureteroscope, the surgeon reaches the kidney through the ureter and fragments stones with a Holmium:YAG laser or other laser systems. The stone fragments are either extracted using baskets or left to pass naturally if sufficiently small.
RIRS is particularly useful for:
- Small to medium-sized renal stones
- Stones in anatomically challenging locations
- Patients requiring a less invasive approach
- Individuals with bleeding disorders where PCNL may carry higher risk
What is Percutaneous Nephrolithotomy (PCNL)?
Percutaneous Nephrolithotomy (PCNL) is considered the gold standard for the management of large and complex kidney stones.
Instead of accessing the kidney through the urinary tract, the surgeon creates a small tract directly into the kidney through the patient’s back. This tract allows the insertion of a nephroscope and specialized instruments to fragment and remove stones.
PCNL offers excellent stone clearance rates, especially for stones larger than 2 cm or complex staghorn calculi.
Common Indications for PCNL
PCNL is recommended for patients with:
- Kidney stones larger than 20 mm
- Staghorn calculi
- Multiple large renal stones
- Hard stones resistant to ESWL
- Stones associated with anatomical abnormalities
- Failed ureteroscopy or RIRS
- Complex lower pole calculi
Why URS and PCNL Are Technically Challenging
Although these procedures are minimally invasive, they require advanced surgical expertise. Success depends on precise instrument handling, accurate visualization, sound anatomical knowledge, and the ability to respond effectively to intraoperative challenges.
Some of the technical challenges include:
- Navigating narrow ureters without causing injury
- Achieving safe renal access during PCNL
- Maintaining clear visualization despite bleeding
- Coordinating fluoroscopic and endoscopic guidance
- Efficient laser lithotripsy while protecting surrounding tissue
- Managing complications such as perforation, bleeding, or infection
- Ensuring complete stone clearance while minimizing trauma
These skills are acquired through structured practice under experienced mentors rather than through observation alone.
Why Hands-On Training is Essential
Watching surgeries, attending lectures, or reviewing surgical videos can build theoretical understanding, but they cannot replace the experience of performing procedures under supervision.
Hands-on training enables surgeons to:
- Develop confidence in handling endoscopic equipment
- Improve hand-eye coordination
- Learn proper guidewire manipulation
- Master ureteroscope navigation
- Perform renal punctures accurately
- Use laser systems safely and effectively
- Handle intraoperative complications
- Make sound surgical decisions in real time
Repeated exposure to live cases allows trainees to internalize each step of the procedure and refine their technique through feedback from experienced faculty.
Limitations of Traditional Residency Training
While residency programs provide a strong foundation in urology, the level of exposure to advanced endourological procedures can vary considerably depending on the institution.
Some common limitations include:
- Limited operative opportunities due to high trainee numbers
- Variable access to advanced equipment such as flexible ureteroscopes and laser systems
- Fewer opportunities to perform procedures independently under supervision
- Inconsistent exposure to complex stone cases
- Time constraints within the residency curriculum
As a result, many practicing urologists seek additional fellowship or hands-on training programs to strengthen their procedural skills and gain confidence in performing advanced URS, RIRS, and PCNL independently.
Mastering Different Types of PCNL: Why Every Endourologist Must Learn Multiple Techniques
Modern endourology has evolved significantly over the last decade. Today, a skilled endourologist is expected to perform more than just conventional PCNL. Depending on the patient’s anatomy, stone size, location, age, bleeding risk, and associated medical conditions, surgeons must choose the most appropriate technique to maximize stone clearance while minimizing complications.
A comprehensive fellowship in Ureteroscopy and PCNL should provide exposure to all major PCNL variants, enabling surgeons to tailor treatment to each individual patient.
1. Standard PCNL
Standard Percutaneous Nephrolithotomy remains the gold standard for treating large and complex renal stones. It typically uses an access tract of 24–30 Fr, allowing the removal of larger stone fragments and facilitating efficient treatment of high stone burdens.
Indications
Standard PCNL is generally recommended for:
- Kidney stones larger than 2 cm
- Partial or complete staghorn calculi
- Multiple large stones occupying different calyces
- Hard stones resistant to ESWL
- Failed ureteroscopy or RIRS
- Anatomically complex kidneys
Surgical Objectives
During training, fellows learn to:
- Plan the optimal calyceal puncture
- Choose the safest access tract
- Minimize renal parenchymal injury
- Achieve complete stone clearance
- Reduce operative time
- Prevent excessive bleeding
A well-trained surgeon understands that success depends not only on removing the stone but also on preserving renal function and ensuring patient safety.
2. Mini-PCNL
Mini-PCNL was developed to reduce the morbidity associated with standard PCNL while maintaining excellent stone clearance.
Using a smaller tract (typically 14–20 Fr), Mini-PCNL causes less trauma to the kidney.
Advantages
Compared with conventional PCNL, Mini-PCNL offers:
- Reduced blood loss
- Lower postoperative pain
- Smaller renal puncture
- Shorter hospitalization
- Earlier return to daily activities
- Better cosmetic outcomes
Ideal Cases
Mini-PCNL is particularly suitable for:

- Pediatric patients
- Solitary renal stones
- Patients at increased bleeding risk
- Moderate stone burden
Training programs should include sufficient Mini-PCNL exposure because it has become increasingly popular in modern urological practice.
3. Ultra-Mini PCNL
Ultra-Mini PCNL represents another advancement in minimally invasive stone surgery.
This technique uses even smaller nephroscopes and access sheaths while maintaining excellent visualization.
Its primary objective is to minimize renal trauma without compromising stone clearance.
Benefits
- Minimal bleeding
- Less postoperative discomfort
- Reduced hospitalization
- Faster patient recovery
- Excellent cosmetic results
Although technically more demanding, experienced surgeons achieve excellent outcomes with proper training.
4. Micro-PCNL
Micro-PCNL utilizes an extremely small puncture tract, making it one of the least invasive percutaneous procedures available.
This approach is particularly useful in carefully selected patients with:
- Small renal calculi
- Pediatric stones
- Difficult anatomical situations
- Patients unsuitable for larger tracts
Because visualization and instrument handling differ from standard PCNL, dedicated hands-on practice is essential.
5. Tubeless PCNL
Traditionally, a nephrostomy tube is left in place after PCNL to provide drainage and tamponade.
However, carefully selected patients may undergo Tubeless PCNL, where no nephrostomy tube is inserted.
Benefits
- Less postoperative pain
- Earlier mobilization
- Reduced analgesic requirement
- Shorter hospital stay
- Greater patient comfort
During fellowship training, surgeons learn the indications and contraindications for tubeless procedures and the criteria for safe patient selection.
Essential Instruments Used in Ureteroscopy Training

Patient Positioning
Depending on surgeon preference and case complexity, the patient may be positioned prone or supine. Trainees learn the advantages and limitations of both approaches.
Retrograde Catheter Placement
A ureteric catheter is inserted to opacify the collecting system and aid renal puncture.
Renal Puncture
This is one of the most critical skills in PCNL. Under fluoroscopic or ultrasound guidance, the surgeon punctures the chosen calyx while avoiding surrounding organs.
Guidewire Placement
A guidewire is advanced into the collecting system to secure access.
Tract Dilation
The access tract is gradually dilated using the chosen dilator system before inserting the working sheath.
Nephroscopy and Stone Removal
The nephroscope is introduced, stones are fragmented using laser or pneumatic lithotripsy, and fragments are extracted.
Final Assessment
The collecting system is inspected for residual stones, bleeding, or injury before deciding whether to place a nephrostomy tube or complete the procedure tubeless.
Learning to Manage Complications
No surgical training is complete without understanding complication management. A quality fellowship prepares surgeons to recognize and respond to intraoperative and postoperative challenges promptly.
Topics commonly covered include:
- Ureteric perforation and false passages
- Ureteric avulsion (recognition and prevention)
- Significant bleeding during PCNL
- Fever, sepsis, and infection control
- Pleural or thoracic complications following upper-pole access
- Injury to adjacent organs such as the colon
