PURPOSE: Ureteral stents are composed of different polymers and it is unclear if stent composition influences patient comfort. We compared the impact of stents composed of firm and soft polymer on patient health related quality of life. MATERIALS AND METHODS: A total of 130 patients requiring insertion of ureteral stents during the treatment of urinary calculi were randomized to receive a stent composed of firm (Percuflex, group 1) or soft (Contour, group 2) polymer. Patients were asked to complete the Ureteric Stent Symptoms Questionnaire, a validated instrument, at weeks 1 and 4 with the stent in situ and 4 weeks after its removal, this served as the main outcome measure. Additional assessments included difficulty in stent insertion and the need for early stent removal. RESULTS: There were 78 men and 38 women in total (61 in group 1 and 55 in group 2) with a mean age of 51 years (range 22 to 79) and no difference in age between the 2 groups (p = 0.9). Comparison of the results of the Ureteric Stent Symptoms Questionnaire survey at weeks 1 and 4 with stent in situ revealed no significant differences in the domain scores of urinary symptoms (p = 0.9 and p = 0.8), pain (p = 0.8 and p = 0.6) and general health (p = 0.6 and p = 0.4). Similarly, there were no differences in the number of days with reduced activities, work performance (p = 0.7) and sexual dysfunction between the 2 groups. A similar number of patients (8 and 7 in groups 1 and 2, respectively) required stent removal earlier than planned due to stent related symptoms. CONCLUSIONS: This randomized study showed no difference in the impact on patient quality of life between ureteral stents composed of firm or soft polymer. |
