Alfuzosin and Mirabegron for Double-J Stent Symptoms

Overview

This prospective randomized controlled trial investigates the effects of alfuzosin, mirabegron, and their combination on stent-related symptoms and outcomes in patients undergoing DJ stent placement after retrograde intrarenal surgery (RIRS) for renal stones. The primary outcomes include stone-free rate and residual fragment status, while secondary outcomes focus on stent-related pain and lower urinary tract symptoms (LUTS). Patients will be randomly assigned to one of four groups: alfuzosin only, mirabegron only, combination therapy, or control. Pain and LUTS will be assessed using validated questionnaires such as the Ureteral Stent Symptom Questionnaire (USSQ) and IPSS.

Retrograde intrarenal surgery (RIRS) is a commonly used minimally invasive procedure for the treatment of renal stones. Postoperative placement of double-J (DJ) stents is often necessary but can result in significant stent-related discomfort and lower urinary tract symptoms (LUTS), which negatively impact patient quality of life. Alfuzosin, an alpha-blocker, and mirabegron, a beta-3 agonist, are pharmacological agents known to reduce stent-related symptoms. This study aims to compare the individual and combined efficacy of these agents on stent-related pain, LUTS, and postoperative stone outcomes. Patients will be evaluated for stone clearance, residual fragments (by imaging), and symptom scores over a follow-up period of 2 to 4 weeks post-RIRS
