Evaluation of Mirabegron Versus Tamsulosin or Their Combination in Treatment of Lower Urinary Tract Symptoms

Ureteric Stent-related Morbidity

Stent related symptoms (SRSs) comprise of complaints such as irritative symptoms, sense of incomplete emptying, flank and suprapubic pain, and incontinence. Mechanical irritation of trigone, urinary reflux, and stent movement are plausible causes for SRSs. Alpha-blockers are the primary medications for ureteral stent-related symptoms. These medications are suggested to patients by the American Urological Association (AUA)/Endourological Society guideline to reduce stent-related symptoms with moderate recommendation. Nevertheless, there are many side effects associated with alpha-blockers such as dizziness, headache, and orthostatic hypotension

Ureteral stents have become an important part of urologic practice since first described the double-J stent . most often urolithiasis. Their use may be associated with significant bothersome symptoms and discomfort. Ureteral stent-related symptoms (SRSs) may occur in up to 88% of patients in mild or more severe degree. Mirabegron is the first and only selective β3-adrenergic receptor agonist agent currently available and it is one of the treatment options for overactive bladder (OAB). Hence, many urologists have been introducing mirabegron therapy for OAB in recent years and because the SRS are similar to OAB symptoms, it may be another treatment option for reducing bladder irritability in patients indwelling DJ stent. It is currently unclear whether mirabegron has a place in the treatment of SRSs. Our study aims to systematically evaluate the efficacy and safety of mirabegron in treating SRSs in comparison to Tamsulosin and their combination in adult patients
