Mini PCNL
Procedure Overview
Mini PCNL is a smaller-tract variation of standard PCNL, using narrower instruments to treat moderate-sized kidney stones with less tissue trauma than the conventional technique.
It offers a middle ground between RIRS and full PCNL — suited to stones too large or dense for a purely scope-based approach, but not requiring the largest access tract.
Who Needs It
Mini PCNL is well suited to moderate-sized kidney stones (roughly 1–2 cm) that are not ideal candidates for RIRS but don't require the larger access of standard PCNL.
Preparation
Preparation is similar to standard PCNL: recent imaging, blood tests, urine culture, and temporary adjustment of blood-thinning medication if applicable.
Step-by-Step Procedure
Anesthesia
General anesthesia is administered.
15–20 minSmall-Tract Access
A narrower puncture is made into the kidney under imaging guidance, smaller than standard PCNL.
15–20 minStone Fragmentation
The stone is broken up using laser energy through the mini-nephroscope.
30–60 minFragment Removal
Stone fragments are cleared through the small access tract.
10–15 minBenefits
- ✓Less bleeding than standard PCNL
- ✓Shorter hospital stay
- ✓Smaller access tract reduces tissue trauma
- ✓Effective for stones not suited to RIRS alone
Recovery Timeline
Hospital stay is usually shorter than standard PCNL, often 1–2 days. Most patients resume light activity within a week.
Technology Used

Frequently Asked Questions
A kidney stone (renal calculus) is a hard mineral deposit that forms in the kidney from concentrated urine. Stones vary in size and type, and small ones may cause no symptoms at all. When should I consult Dr. Raju R?
Bladder stones form directly in the bladder, usually because it isn't emptying fully, unlike kidney stones which form in the kidney. When should I consult Dr. Raju R?
Classic stone pain starts suddenly in the flank or back and radiates to the groin, often in waves, with nausea and sometimes blood in the urine. When should I consult Dr. Raju R?
Stones form when urine is too concentrated with calcium, oxalate, or uric acid. Low water intake, salty or high-protein diets, obesity, and family history all raise the risk. When should I consult Dr. Raju R?
Diagnosis uses a urine test, blood test, ultrasound, and usually a CT KUB scan, the most accurate way to see stone size and location. When should I consult Dr. Raju R?
