Standard Versus Flexible and Navigable Suction Ureteral Access Sheath in Pediatric Flexible Ureterorenoscopy for Renal Stones < 2 cm (FANS-UAS)
Standard Versus Flexible and Navigable Suction Ureteral Access Sheath in Pediatric Flexible Ureterorenoscopy for Renal Stones < 2 cm : A Randomized Controlled Study

Detaljert beskrivelse
Pediatric urolithiasis is an increasingly recognized condition associated with substantial morbidity and recurrence risk. Flexible ureterorenoscopy has become an established minimally invasive treatment option for renal stones smaller than 2 cm. The use of ureteral access sheaths facilitates repeated upper urinary tract access and may improve operative efficiency; however, concerns regarding ureteral trauma remain.
Recently developed suction-assisted ureteral access sheaths have been introduced to improve visibility, facilitate fragment evacuation, and reduce intrarenal pressure. Although promising results have been reported in adults, evidence in pediatric patients remains limited.
This prospective randomized controlled trial will compare a standard ureteral access sheath with a Flexible and Navigable Suction Ureteral Access Sheath (FANS) in pediatric patients undergoing flexible ureterorenoscopy for renal stones less than 2 cm.

This outcome measure will evaluate the requirement for additional interventions to achieve complete stone clearance or manage residual fragments.
It will be assessed by recording the percentage of participants who require any secondary or ancillary surgical procedures (such as second-stage ureterorenoscopy, shock wave lithotripsy, or temporary stenting) within 30 days postoperatively
