Standard Versus Flexible and Navigable Suction Ureteral Access Sheath in Pediatric Flexible Ureterorenoscopy for Renal Stones < 2 cm

Condition(s) studied

Investigational drug(s) / intervention(s)

Standard Ureteral Access Sheath (Boston Scientific).: Standard UAS (Length: 28-35 cm, Size: 10/12 Fr or 9.5/11.5 Fr)

Flexible and Navigable Suction UAS (ClearPetra).: Suction evacuation ureteral access sheath (Length: 30-35 cm, Size: 10/12 Fr or 11/13 Fr) with terminal flexible end

Study summary

This randomized controlled trial aims to compare the efficacy and safety of a Flexible and Navigable Suction Ureteral Access Sheath (FANS) versus a standard ureteral access sheath during flexible ureterorenoscopy (FURS) in pediatric patients with renal stones less than 2 cm. The study will evaluate stone-free rates. operative time. intraoperative parameters. operative and postoperative complication and the need for any auxiliary procedures. Sixty pediatric patients will be randomly allocated into two equal groups and treated at the Urology Department, Tanta University.

Eligibility

Primary outcome measure(s)

• Stone-free rate (SFR) — 1 month postoperatively
  Absence of residual fragments or presence of clinically insignificant residual fragments measuring \< 3 mm, assessed by postoperative CT scan.
