Abstract

Objective: To compare stent-related symptoms (SRS) associated with conventional ureteric JJ stent (CUS) placement and SRS associated with placement of a modified complete intra-ureteric stent (CIUS) with extraction suture, designed to minimize SRS, using the validated Ureteral Stent Symptom Questionnaire (USSQ). Materials and Methods: We randomized 124 patients who had undergone uncomplicated ureteroscopic lithotripsy into a CIUS and a CUS placement group. USSQ scores were evaluated on postoperative days 1 and 7 (just before stent removal) and 4 weeks after stent removal (control values). Pain scores on a visual analogue scale (VAS) after stent removal were also recorded. Subdomain analysis of all SRS and stent-related complications were also compared. Results: No significant intergroup differences were found in the domain scores for urinary symptoms (P = 0.74), pain (P = 0.32), general health (P = 0.27), work (P = 0.24), or additional problems (P = 0.29). However, a statistically significant difference was noted in VAS scores (P = 0.015). Analysis of subdomains of USSQ item scores showed the CIUS group had significantly better scores for urge incontinence (1.21 vs 1.00; P ≤ 0.001), discomfort on voiding (2.07 vs 1.50; P ≤ 0.001), difficulties with respect to light physical activity (1.131 vs 1.00; P ≤ 0.001), fatigue (1.84 vs 1.57; P = 0.002), feeling comfortable (3.68 vs 3.16; P = 0.003), need for extra help (1.96 vs 1.00; P ≤ 0.001), and change in duration of work (4.27 vs 1.86; P ≤ 0.001). However, the patients in the CIUS group were sexually inactive for the time during which the stent was indwelling (mean: 7.34 days). There was no difference in complication rates between the two groups. Conclusion: The use of a CIUS with strings after Ureteroscopy decreases SRS.
