Ureteral Stent-Related Symptoms and Pharmacotherapy: A Brief Narrative Review.

Abstract

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included. The available reviews and articles associating the use of drugs with stent-related symptoms (SRS) provide conflicting results. Most of them show a clear benefit of alpha blockers, particularly alfuzosin, on treating urinary SRS, and hence there is a strong recommendation for the use of alpha blockers for the treatment of SRS in the guidelines of the European Association of Urology. Anticholinergics and mirabegron have shown a significant benefit in dealing with irritative bladder symptoms. In contrast, the findings for combination therapies are contradictory, with some studies showing that combination therapy is no superior to monotherapy with regards to most of the subsets of the Ureteral Stent Symptom Questionnaire (USSQ), whereas others present a clear benefit of combination therapies, specifically silodosin and solifenacin, in treating stent-associated lower urinary tract symptoms (LUTS), in comparison with any other type of monotherapy or combination therapy. Many studies suggest that some categories of pharmacotherapy, such as alpha blockers, can alleviate SRS. However, there is conflicting evidence concerning most other types of medical treatment. Randomized trials with the largest number of patients are needed to investigate the effectiveness of novel approaches on SRS.
