A Comparison of the Outcomes of Pediatric Percutaneous Nephrolithotomy Between Different Age Groups: Single Center Experience

Objective: We aimed to present the outcomes and complications of percutaneous nephrolithotomy (PCNL) performed during childhood in a comparative manner among different age groups. Material and Methods: We retrospectively evaluated children under 18 years of age who underwent the PCNL operation between 2008 and 2016 at our clinic. Cases were further divided into three age categories as >6, 6–11, and 12–17 years. Demographic data, and the preoperative and operative data were compared between the selected age groups. We used kidney-ureter-bladder radiography (non-contrast-enhanced computed tomography in cases with non-opaque stones) that was performed 6 weeks postoperatively for the assessment of residual stones (≥4 mm). Postoperative complications were recorded according to the modified Clavien classification. Residual stone rates and complications of PCNL were compared between the three age groups.
