Mini PCNL involves creating a smaller tract (≤20 Fr) from the skin into the kidney to access and remove stones, typically using miniaturized instruments.
Who Needs ?
- Patients with kidney stones >1.5 cm
- Stones that are hard or resistant to other treatments
- Stones in anatomically challenging locations
- When ESWL or RIRS is not effective or feasible
How the Procedure Works:
- Patient under general or regional anesthesia
- Imaging-guided percutaneous puncture into the kidney
- Tract dilation (to 14–20 Fr)
- Stone visualization and fragmentation (with Holmium:YAG laser or ultrasonic device)
- Stone fragments are removed using suction or forceps
- A nephrostomy tube or DJ stent may be placed
Advantages:
- Minimally Invasive
- Reduced Bleeding
- Less Postoperative Pain
- Faster Recovery Time
- Lower Risk of Complications
Limitations / Risks:
- May be less efficient for large or staghorn stones
- Potential for infection, bleeding, or injury to nearby organs
- Longer operative time than standard PCNL in some cases
