The Impact of Endourological Experience on Flexible Ureteroscopy Outcomes and Performance at Different Levels of Expertise: Retrospective Multifactorial Analysis

Abstract

Introduction: The aim of this study was to analyze the influence of residents' participation in flexible ureteroscopy (fURS) on intra- and postoperative outcomes. Materials and Methods: Intra- and postoperative parameters were compared in a retrospective monocentric setting between 3 groups: "resident group" (47 cases) for surgeries performed by experienced residents alone, "consultant group" (245 cases) for surgeries performed by consultants alone, "resident plus consultant group" (124 cases) for training surgeries between September 2013 and June 2017. Results: Patients operated by residents alone had a significantly smaller median kidney stone diameter (5.0 vs. 7.0 mm for "consultant group" and 6.0 mm for "resident plus consultant group," p = 0.011), shorter operating time (median 47.0 vs. 63.0 and 77.0 min, p < 0.001) and fluoroscopy time (median 39.0 vs. 69.5 and 89.0 s, p < 0.001), as well as shorter postoperative hospital stay (p = 0.013). The laser application rate was the smallest in the "resident group" (10.64 vs. 31.43 and 29.84%, p = 0.009). Univariate analysis revealed no relevant differences regarding flexible ureteroscope defect rate, postoperative stone-free rate, or ≥2 Clavien-Dindo classification complications between the groups (p > 0.05). Conclusion: A proper case selection of less complicated cases, especially without laser application, could balance the experience deficit of the residents. fURS can be incorporated as a part of residents' training without an impact on fURS device defect rate or clinical outcomes.
