Abstract

Introduction: Distal ureterolithiasis, characterized by stones in the lower ureter, poses significant challenges in clinical management. Medical expulsive therapy (MET) using Tamsulosin is a common non-invasive treatment, but its efficacy can be limited, especially for stones larger than 5 mm. Deflazacort, a corticosteroid with anti-inflammatory properties, may enhance the effectiveness of Tamsulosin by reducing ureteral inflammation and facilitating stone passage.

Methods: This prospective, randomized controlled trial enrolled 80 patients with distal ureteral stones <8 mm. Participants were randomly assigned to receive either Tamsulosin alone or Tamsulosin with Deflazacort for 28 days. Primary outcomes included stone expulsion rate and time, while secondary outcomes were pain reduction, analgesic use, and adverse effects.

Results: The combination therapy group showed a higher expulsion rate (85% vs. 70%) and significantly faster expulsion time (10.1 days vs. 13.9 days, p=0.006). Pain reduction was greater in the Deflazacort group, with fewer colic episodes and reduced analgesic requirements. Adverse effects were comparable between the groups, with no significant increase in major side effects in the combination therapy group.

Conclusion: The addition of low-dose Deflazacort to Tamsulosin significantly improves stone expulsion rates, reduces expulsion time, and lowers pain levels in patients with distal ureterolithiasis, without increasing major adverse effects. This combination may represent a superior treatment option in MET for distal ureteral stones.
