Assessing the Impact of Ureteral Stent Design on Patient Comfort

We assessed the near term comfort of newly designed ureteral study stents or marketed control stents, including Polaris and Percuflex stents. Study stents had distal 6Fr pigtail ends with 3Fr or less loops. Decreased material in situ was hypothesized to enhance comfort. Usefulness of the patient self-administered Ureteral Stent Symptoms Questionnaire (Stone Management Unit, Southmead Hospital, United Kingdom) was assessed.
