The aim of this study was to compare the HRQOL of patients with residual stone fragments after surgical intervention for kidney stones to patients that are stone-free using the disease-specific Wisconsin Stone Quality of Life (WISQOL) questionnaire. METHODS: With IRB approval, 282 adult patients who underwent surgical intervention for kidney stones at 4 centers completed a WISQOL questionnaire. We retrospectively collected surgical data including presence of residual fragments on post-operative imaging. We calculated standardized WISQOL total and domain scores (0-100), including social functioning (D1), emotional functioning (D2), stone-related impact (D3) and vitality (D4). Scores were compared between patients with residual fragments to those who were stone-free on the laterality of the surgical intervention. RESULTS: Demographics did not differ between groups, overall mean age 55.2 ± 13.7 and 51.8% male. There was no significant difference in total WISQOL score for patients with residual stone fragments (n=148) compared to patients that were stone-free (n=134), 112.9 ± 25.8 vs 117.3 ± 22.8 respectively, (p=0.17). In addition, there was no significant difference for individual domain scores (D1: 82.8 vs 87.4, p= 0.13, D2: 72.0 vs 77.6, p= 0.11, D3: 72.9 vs 76.0, p= 0.32, D4: 70.5 vs 71.7, p= 0.75). However, compared to stone-free patients those with residual stone fragments reported significantly more frustration with their situation (4.08 ± 1.16 vs 3.73 ± 1.40, p = 0.03). Furthermore, patients with residual fragments who underwent secondary stone surgery were found to have significantly lower total WISQOL score (87.3 vs 114.2, p= 0.04). CONCLUSIONS: Preliminary evidence suggests that stone-free status after surgical intervention is not associated with better HRQOL. Further surgical intervention on residual fragments to achieve stone free-status may actually result in worse HRQOL. These results suggest that in a properly counseled patient, surveillance of non-obstructing residual stone fragments may be an acceptable management strategy. Identifying that patients with residual fragments may have more frustration with their situation may help to improve patient counseling and properly set expectations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
