PURPOSE: We compared intraureteral stent placement (CIU-SP) with conventional stent placement (C-SP) regarding the stent-related symptoms.
METHODS: We randomized patients who underwent ureteroscopic lithotripsy into two groups. In CIU-SP group, a 16-cm or 18-cm stent was placed with its distal end above the ureterovesical junction. In C-SP group, a 22-cm or 24-cm stent was placed in a conventional method. Stent-related symptoms were assessed with the Ureteral Stent Symptom Questionnaire (USSQ) before the stent was removed, around 7 days after the operation. The primary outcome was the urinary symptoms; the secondary outcomes included postoperative pain and quality of life.
RESULTS: We randomized 103 patients, of which 91 (45 in CIU-SP and 46 in C-SP) entered the final analysis. Regarding the primary endpoint, the CIU group had less urinary symptoms; the mean USSQ urinary symptom score was significantly lower in the CIU-SP versus C-SP group (25.5 ± 6.3 vs 31.7 ± 5.9, P < 0.001). The CIU-SP group also had more favorable profiles in the following outcomes: lower USSQ body pain score (15.5 ± 5.3 vs 20.1 ± 5.2, P < 0.001), lower overall pain score (3.2 ± 2.2 vs 5.7 ± 2.3, P < 0.001), less number of pain site (1.0 ± 0.9 vs 1.7 ± 0.9, P = 0.001, lower USSQ general health score (10.4 ± 3.7 versus 13.9 ± 3.4, P < 0.001), and lower USSQ work performance score (5.2 ± 3.3 versus 6.7 ± 2.8, P = 0.033). In either group, there was no complication of Clavien-Dindo Class 2 or greater.
CONCLUSION: The complete intraureteral placement significantly decreases stent-related urinary symptoms and pain. It is also associated with better postoperative general health condition and is less likely to limit physical activity and work ability.
