Abstract
Treatment of pediatric stone disease is a challenge, more so, in the case of infants. Infantile anuria due to calculus disease is rare, as pre-renal causes predominate. Retrograde intrarenal surgery is a less often sorted modality in infants, due to the lingering skepticism regarding handling pediatric ureters and urethra. We hereby present the first case report of bilateral simultaneous RIRS, in a 4 month old male child. With better stone free rates than ESWL and a lesser incidence of major complications, we opted for RIRS in this child, taking advantage of the pre-stented ureter.
