Tamsulosin Versus Mirabegron in Relieving Ureteric Stent-Related Symptoms: A Prospective, Double-Blinded, Randomized Controlled Trial.

Introduction Alpha-adrenergic blockers like tamsulosin are widely used in the treatment of stent-related symptoms due to ureteric stents. Recently, mirabegron has emerged as a potential alternative. So, our study aimed to compare the effect of mirabegron and tamsulosin on ureteric stent-related morbidity. Methods In this randomized controlled study, 80 patients undergoing uncomplicated ureteroscopic lithotripsy with double J stenting for ureteric stones were enrolled. They were divided into two groups: Group A (n=40) received mirabegron (25mg) and Group B (n=40) received tamsulosin (0.4mg). Outcomes were assessed using the Ureteral Stent Symptom Questionnaire (USSQ), International Prostate Symptoms Score (IPSS), and the visual analog pain scale. The t-test and the Chi-square test were utilized to study the efficacy of the interventions across both groups. Results The USSQ urinary symptom score (25.5 vs 33.45; p < 0.001) and body pain score (16.15 vs 26.02; P < 0.001) were significantly lower in the mirabegron group. However, the general health score (17.0 vs 17.28; p = 0.62) and work performance score (7.6 vs 8.0; p = 0.28) did not show a significant difference. The storage symptom score was significantly lower in the mirabegron group (3.98 vs 5.1; p = 0.001). Furthermore, the mirabegron group reported a better quality of life score (2.18 vs 3; p < 0.001). Conclusion Mirabegron has been shown to reduce urinary symptoms associated with ureteric stents and also results in a better quality of life when compared with tamsulosin. However, large-scale, prospective, multicentric studies are further required to holistically evaluate and comprehend the beneficial effects of mirabegron on stent-related morbidity.
