Oner S, et al. - In this study, researchers gauged the safety and morbidity of single upper pole access in pediatric patients with renal stones who underwent percutaneous nephrolithotomy (PCNL). Upper pole access could be performed without serious complications, and it provided outcomes that were similar to other (middle and lower) pole accesses. It served as a safe and effective approach for PCNL and presented as a good alternative for the removal of renal stones in pediatric patients.
