We aimed to compare the safety and tolerability of the 2 stent types used in our centre. METHODS: After institutional ethical committee approval, we prospectively randomized patients planned for flexible URS for renal stones between July 2022 and May 2023 to catheterization with single-J stents (removed <24 h after the surgery - Group J) or double-J stents (extracted in a subsequent appointment - Group JJ). Exclusion criteria included ureteral stones, and any urinary tract alteration. Primary outcomes were emergency department admission, postoperative complications and reintervention rate. A symptom questionnaire was applied at postoperative weeks 1 (W1) and 4 (W4). RESULTS: We included 97 patients: 50 in Group J and 47 in Group JJ. Baseline characteristics did not differ between groups (Table 1). Double-J stents were removed after a median of 28 days (IQR 21-36). 82% of Group J and 83% of Group JJ patients answered the symptom questionnaires (p=.90).Main outcomes results are described in Table 2. Emergency department admission, total complications, and the need for reintervention due to grade ≥III complications were not statistically different between groups. LUTS were significantly less severe in Group J. Lumbar and supra-pubic pain were not significantly different at W1, but they were less frequent in Group J at W4. 40% of the JJ patients removed the stent before the W4 questionnaire, which might have underestimated the differences between groups. Stone-free was similar in both groups (76% in Group J and 76.6% in Group JJ, p=.37). CONCLUSIONS: Single-J stents removed <24 h after URS were not associated with more post-operative complications, readmission, or reintervention, and they were better tolerated, especially 4 weeks after the surgery. Therefore, they seem a viable alternative for complete flexible URS, reducing costs, hospital visits for stent removal and the associated complications like stent-related symptoms and forgotten stents.
