Comparison of Silodosin Versus Tamsulosin on Passage of Acutely Obstructing Ureteral Calculi (History of Last 4 Weeks) in Medical Expulsive Therapy

Phase 4 Interventional Getz Pharma · NCT05977647

This study is testing if a medication called silodosin can help adults with small stones in their ureters pass them more easily without needing surgery.

What this trial studies

This clinical trial investigates the use of α-blockers, specifically silodosin, as a medical expulsive therapy (MET) for patients with distal ureteric stones (DUS) located in the lower third of the ureter. The study aims to confirm the efficacy and safety of this non-invasive treatment option compared to traditional invasive procedures. Participants will be adults aged 18 to 70 with specific eligibility criteria, including the presence of a single, unilateral, radiopaque ureteral calculus. The trial will assess the therapeutic benefits of α-blockers, which have shown promising results in previous studies.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 70 with a single, unilateral ureteral stone located in the distal third of the ureter.

Not a fit: Patients with existing renal stones in other locations, severe hydronephrosis, or those currently taking α-blockers may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a safer and less invasive option for patients suffering from ureteric stones, potentially reducing the need for surgical interventions.

How similar studies have performed: Previous studies have shown significant therapeutic benefits of α-blockers for treating distal ureteric stones, indicating a promising approach.
