Silicone vs. Polyurethane Stent: The Final Countdown

Abstract

Ureteric stents are conventionally used in daily urological practice. There is ongoing debate on the superiority of different stent materials, particularly in terms of patient tolerance. We conducted a literature review to compare silicone stents and stents made of other materials from a patient tolerability perspective. We conclude that silicone stents are better tolerated but further research is required.

Investigation of quality of life and anxiety level of patients who have undergone pigtail placement

“…23,24 Scientific advances in material stent design, alleviating symptoms and leading to rapid recovery, are worth noting. [25][26][27] In their review, Mathias and colleagues 26 looked for the advantages of different stent materials with respect to symptomatology (a combination of localized inflammation, elevated bladder pressure causing reflux of urine towards the kidney and reduced ureter peristalsis and bladder irritation). They report that the three factors that affect stent performance are their design, the material they are made of and any surface coating they may have.…”

“…They report that the three factors that affect stent performance are their design, the material they are made of and any surface coating they may have. 26 They therefore consider that the ideal stent should have excellent flow and be easy to insert and remove, radio-opaque, biologically inert, coated to prevent infection, flexible with good tensile strength and, above all, cause minimal symptoms and complications. They conclude that silicone stents have most of these properties.…”

Efficacy of Pregabalin, Solifenacin, or Combination Therapy for Ureteral Stent Related Symptoms: A Systematic Review and Meta-Analysis

“…21 Silicone also has a lower potential for encrustation. 36 New stent shapes that might lessen tissue irritancy and urine reflux have lately received a lot of attention in the development of innovative stent designs. 1 "Pigtail suture stent" at the distal end can reduce USRS more than a J-shaped stent.…”

“…1 "Pigtail suture stent" at the distal end can reduce USRS more than a J-shaped stent. 36 According to a meta analysis, urinary symptoms and pain are worse as the stent diameter gets bigger. As a result, smaller diameter stents ought to be chosen.…”
