Current role of microperc in the management of small renal calculi

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrolithiasis Management

Background:

• Percutaneous nephrolithotomy (PCNL) is a standard treatment for kidney stones.
• Micropuncture techniques aim to reduce invasiveness in renal access.
• Microperc and Mini-microperc represent advancements in single-step percutaneous renal access and lithotripsy.

Purpose of the Study:

• To evaluate the safety and efficacy of the Microperc technique for renal calculi management.
• To assess the utility of Microperc in adult and pediatric populations, including ectopic kidneys and bladder stones.
• To compare Microperc with existing treatments like retrograde intrarenal surgery.

Main Methods:

• Microperc involves single-step percutaneous renal access and lithotripsy using a 16 G micropuncture needle.
• Mini-microperc utilizes an 8 Fr sheath for probe insertion and suction.
• Evidence synthesis from available studies on Microperc procedures.

Main Results:

• Microperc demonstrates safety and efficiency in managing small renal calculi.
• The technique is applicable to both adult and pediatric patients.
• Successful application in ectopic kidney stones and bladder calculi has been reported.
• High stone clearance rates and lower complication rates are associated with Microperc.

Conclusions:

• Microperc is a safe and effective minimally invasive option for kidney stone treatment.
• Its high stone clearance and low complication rates make it a viable alternative to retrograde intrarenal surgery.
• The technique shows promise for various stone locations, including ectopic kidneys and the bladder.
