Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ultrasound
Before completing retrograde intrarenal surgery, a complete endoscopic examination will be performed along with ultrasound by the same endourologist to determine the size of the largest residual fragment.
Ultrasound
Before completing retrograde intrarenal surgery, a complete endoscopic examination will be performed along with ultrasound instead of fluoroscopy by the same endourologist to determine the size of the largest residual fragment.
Fluoroscopy
Standard of care, control Before completing retrograde intrarenal surgery, a complete endoscopic examination will be performed along with fluoroscopy by the same endourologist to determine the size of the largest residual fragment.
