Objective:To investigate the feasibility of improving quality of life through outcome self-reporting and clinical intervention based on the Ureteral Stent Symptom Questionnaire(USSQ)for patients with upper tract urolithiasis.Methods:We enrolled 106 patients with upper urinary tract calculi from June 2023 to June 2024 who underwent ureteral stent placement at The First Affiliated Hospital of Chongqing Medical University.We applied the USSQ to monitor the patients'outcomes through their self-reports,and used the data to inform clinical interventions.The feasibility of this USSQ-based approach for improving patients'quality of life was evalu-ated.Results:The main symptoms after ureteral stent placement were pain and hematuria,while frequency,urgency,fever,and sexual problems were less common.The USSQ score was highest on the third day after operation,and thereafter declined in all the dimensions.except the additional problem.After intervention,the total USSQ score(57.5±10.1 vs.51.6±8.9,t=2.981,P=0.004)and urinary symptom score(30.8±5.3 vs.26.7±5.6,t=3.478,P<0.001)were significantly decreased.USSQ-based outcome self-reporting and clinical intervention could reduce symptom scores and improve patients'quality of life.Conclusion:USSQ-based outcome monitoring and management are feasible and effective for improving the quality of life of patients with upper tract urolithiasis.

Objective To study the differences in dynamic stability characteristics between older and young adults during continuous turning and walking in different directions.Methods Fifteen healthy older adults and 15 healthy young adults were recruited to complete continuous clockwise and counterclockwise figure-of-8 walk.A three-dimensional motion capture system was used to collect kinematic data based on 43 bone markers.The gait and velocity of the center of mass parameters were determined using V3D software.The margins of stability in both the anterior and medial direction at characteristic moments were calculated.Results Compared with clockwise turning,the step width of the inner leg increased and the anterior margin of stability of the inner leg at the toe-off instant decreased during counterclockwise turning in young adults.Meanwhile,there were no significant differences in the above parameters for older adults.Conclusions Both the age and turning direction affected the forward dynamic stability of the inner leg at the toe-off instant.Healthy older adults adopted more cautious strategies to maintain anterior and medial stability during continuous walking.It is recommended that older adults should increase turning training in daily life to improve their medial-lateral control capability and confidence in turning.
