Efficacy And Safety Of Antegrade Uretroscopic Lithotripsy Versus Retrograde Ureteroscopic Lithotripsy In The Treatment Of Upper Ureteric Stones Measuring > 10 mm In Maximum Dimension. A Randomized Comparative Study

Ain Shams University·interventional·Posted Jan 23, 2026·Updated Jan 23, 2026

In Brief

A clinical study evaluating antegrade flexible ureteroscopy for group A and retrograde flexible ureteroscopy For group B for Upper Ureteric Stones. Completed, enrolled 100 participants across 1 site.

Detailed Summary

This study aims to assess the efficacy and safety of antegrade flexible ureteroscopic lithotripsy in treating upper ureteric stones \>10 mm in maximum dimension and impacted upper ureteric stones irrespective of size in comparison to retrograde ureteroscopic lithotripsy and evaluate feasibility, adverse events, hospital stay and cost benefit of both techniques

Interventions

antegrade flexible ureteroscopy for group Aprocedure

The antegrade approach with this stone size will further prove the superior stone free rate compared with the retrograde approach, widen the indication for the antegrade approach and prove the more favorable perioperative safety profile

retrograde flexible ureteroscopy For group Bprocedure

he antegrade approach with this stone size will further prove the superior stone free rate compared with the retrograde approach, widen the indication for the antegrade approach and prove the more favorable perioperative safety profile
