MINI PCNL in a pediatric population.

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Nephrolithiasis Management

Background:

• Percutaneous nephrolithotomy (PCNL) is a standard treatment for large kidney stones.
• Pediatric stone management requires specialized techniques to ensure safety and efficacy.
• MINI PCNL offers a less invasive approach for pediatric patients.

Purpose of the Study:

• To evaluate the initial experience and outcomes of MINI PCNL in a pediatric population.
• To assess the safety and effectiveness of using a miniature nephroscope and a 16F metal access sheath for pediatric renal stone extraction.

Main Methods:

• Prospective documentation of demographic details, procedural information, and posttreatment outcomes for pediatric patients undergoing MINI PCNL.
• Evaluation of 23 MINI PCNL procedures performed on 12 pediatric patients (ages 1.6–14.6 years) between August 2007 and September 2010.
• Inclusion of patients with various stone burdens, including staghorn calculi, treated via primary or secondary access tracts.

Main Results:

• A successful access rate of 91.3% was achieved in 23 MINI PCNL procedures.
• The primary stone-free rate was 83.6%, increasing to 90.5% after residual fragment treatment.
• The mean operative time was 109.4 minutes with a mean X-ray screening time of 4.5 minutes.
• One case of postoperative hydrothorax required a chest drain; other complications were minor infections.

Conclusions:

• MINI PCNL is a safe and effective minimally invasive option for managing renal stones in children.
• The technique demonstrates favorable stone-free rates and a low complication profile in the pediatric population.
• Initial experience supports the utility of MINI PCNL as reported in previous studies.
