Should flexible ureterorenoscopy be the first-line treatment option for renal calculi?

Abstract

While first-line treatment option for pediatric renal calculi, 1.5-2 cm in size, was open surgery in the past, percutaneous nephrolithotomy (PNL) is now the first-line treatment option in accordance with EUA pediatric guidelines. However, mini rigid ureterorenoscopy (URS) and the laser props of flexible URS have started to be used in the removal of these calculi. The present study aimed at conveying our experience in using flexible URS and laser on the removal of right renal calculus, 16 mm in size, in a 1-year-old male pediatric patient.
