The safety and efficacy of doxazosin in medical expulsion therapy for distal ureteric calculi: A meta-analysis

An update on efficacy and safety of alpha-blockers in the treatment of distal ureteric stones: narrative review

Background

Alpha-blockers prescribed as medical expulsion therapy (MET) have replaced minimally invasive procedures as the primary line of treatment for minor ureteric stones. This study aims to investigate the efficacy of MET with alpha-blockers in terms of stone expulsion rate and time and evaluate the safety of several alpha-blockers.

Methodology

Google Scholar, PubMed, and Web of Science databases were searched for relevant publications using keywords published between December 2013 and August 2021. Additional relevant research was found by looking through the references in the articles.

Results

To determine the efficacy and safety of alpha-blockers as a medical expulsive therapy for the management of distal ureteral stones, 15 studies were included, 12 randomized control trials, 2 retrospective observational studies, and 1 prospective study. The most commonly studied primary endpoint was stone expulsion rate and time. According to findings, silodosin appears to be more effective than other alpha-blockers. The data revealed no life-threatening adverse effects were associated with alpha-blockers.

Conclusion

Alpha-blockers are recommended as the first-line therapy for distal ureteral stones. Silodosin was the most efficacious medicine, according to the data. The side effects of alpha-blockers, on the other hand, were minor, consisting primarily of orthostatic hypotension. The alpha-blocker choice differs from urologist to urologist in the management of MET, depending on their experience and the patient's condition.
