Abstract
- Introduction and Objective: Ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) are standard treatments for intermediate-size (15–20 mm) kidney stones but differ in their postoperative recovery, stone-free rates, and complication risks. We aimed to evaluate what affects patient treatment preferences. Methods: Patients with urinary stone disease completed a choice-based conjoint analysis exercise assessing four treatment attributes associated with URS and PCNL. A sensitivity analysis using a market simulator was performed, and the relative importance of each attribute was calculated. Differences in treatment preferences by demographic subgroup were assessed. Results: A total of 58 patients completed the conjoint analysis exercise. Stone-free rate was the most important treatment attribute, while the length of hospital stay and cosmesis were less important. Overall, sensitivity analysis based on market simulation scenarios predicted an almost equal preference for URS (52.4%) compared with PCNL (47.6%) for treatment of an intermediate-size stone. Older patients (>65 years old) expressed their stronger preferences for lower infection rates and shorter hospital stays, and were more likely to prefer URS (67.2%, 95% confidence interval [CI]: 52% to 82.5%) compared with younger patients (20–34 years old) (20.3%, 95% CI: 0% to 41.5%) who preferred higher procedure success rates and fewer repeat procedures. Conclusion: Conjoint analysis predicts nearly equal patient preference for URS or PCNL for the treatment of intermediate-size kidney stones. Older patients prefer the lower urinary tract infection risk and shorter hospital stay associated with URS, while younger patients prefer higher stone-free rates associated with PCNL. These results can help guide urologists in counseling patients and improve the shared decision-making process. [ABSTRACT FROM AUTHOR]
