STPEDISET: A novel innovation for percutaneous nephrolithotomy in children.

The aim of this study was to report the outcomes of PCNL in patients in whom the Short and Thin Pediatric Set (ST PEDISET) had been used.Data from 21 patients (11 boys and 10 girls) who underwent PCNL for renal stones using the ST PEDISET between April 2013 and February 2015 were analyzed retrospectively. The patients were evaluated by plane radiography and USG after surgery.In total 21 children (11 boys and 10 girls) with a median age of 13months (range 5months to 4years) who underwent PCNL were included in the study. The median stone burden was 16mm (range 10-36mm). The success rate was 85.7%. Sixteen patients (76.2%) were stone free and two patients (9.5%) had clinically insignificant residual fragments (CIRF). The median length of hospital stay was 4days (range 2-9days).The data of this study clearly show that the ST PEDISET is safe, effective and ergonomic for percutaneous nephrolithotomy in preschool-age children. This study indicates the need for randomized trials on larger cohorts to confirm these findings, and thus improve the surgical procedure.
