Comparative evaluation of flexible ureterorenoscopy and mini-percutaneous nephrolithotomy for the management of renal pelvic stones less than 2 cm with high attenuation value in pediatric patients: a prospective randomized study

Key Points

• Mini-percutaneous nephrolithotomy shows superior effectiveness for managing renal pelvic stones in pediatric patients, particularly those with high attenuation value.
• The study observed that patients undergoing mini-PCNL had significantly quicker stone-free rates, achieving 90 percent compared to 70 percent in the flexible ureterorenoscopy group.
• Prospective randomized study assessing renal pelvic stones utilized advanced imaging metrics to guide treatment choices in children.
• Findings highlight the need to consider high attenuation values when selecting interventions for pediatric renal stones.
