Ureteral stents: A brief narrative review of the different polymeric types, their characteristics, and their connection to stent-related symptoms

Background: In routine urological practice, pigtails are frequently utilized to relieve blockage. Early signs of pigtail problems include pain, lower urinary tract symptoms, pain, hematuria (54%) and fever. Seventy percent of patients experience irritable voiding symptoms, and 80% of patients or even more report pain interfering with everyday activities. Methods: This article's goal is to evaluate the various polymeric stents that are currently on the market. In addition, a review of their fundamental bioqualities is conducted, and a connection between their physical attributes (length, size, and composition) and stent-related issues is looked into. For this review, extensive Medline, PubMed, and literature research from 1987 to January 2023 was conducted. Lower urinary tract complaints, ureteral stents, “pigtail,” “materials,” “characteristics,” or “properties” were the search terms employed. Results: The reviews and publications that are now accessible linking certain materials to stent-related symptoms offer contradictory conclusions, and the majority of research do not specify the precise properties of the materials utilized. The results of the studies on the relationship between stents length and diameter and symptoms connected to stents are likewise inconclusive, despite the fact that there are several studies on this topic in the literature. Conclusion: Numerous studies imply a connection between the various types and properties of the utilized stents and stent-related complaints. However, the available data did not fully support this claim, necessitating additional research
