The experience of patients who choose observation or surgery for kidney stones has not been well established. We compared these patients using qualitative interviews, the Wisconsin Quality of Life questionnaire (WISQOL), and the Cambridge Renal Stone Patient Reported Outcome Measure (CReSP). Adult patients with upper tract urinary calculi for whom observation or intervention were options underwent qualitative interviews at baseline and at 2 months. WISQOL and CReSP were administered at baseline, and at 6-16 weeks post operatively if surgery was selected. Comparisons in patient experiences and quality of life measures were performed between groups. Among 15 patients who opted for surgery and 10 patients who opted for observation, we identified major themes in patient experiences related to context, health care episodes, patient responses, and perceived outcomes. A conceptual framework for the domains of patient experience during kidney stone disease was developed, which can be used by clinicians and patients to shape discussion. Baseline standardized WISQOL and CReSP scores were comparable between groups. In the surgery group, both WISQOL and CReSP scores improved after surgery (WISQOL 58 to 83, higher is better, p = 0.003; CReSP 31 to 23, lower is better, p = 0.009). Patients who underwent surgery for kidney stones reported improvements in quality of life after treatment via WISQOL and CReSP. A conceptual framework was developed for the patient experience of kidney stones which provides a common language for patients and clinicians.
