Flexible ureteroscopy in extreme elderly patients (80 years of age and older) is feasible and safe.

ABSTRACT

PURPOSE: To compare the safety and efficacy of RIRS in patients ≥ 80 years to a younger population. METHODS: We retrospectively compared the data from patients ≥ 80 years of age undergoing RIRS with the data of a group of patients from 18 and < 80 years. Perioperative outcomes, complications and emergency department visits were compared between two groups. RESULTS: A total of 173 patients were included in the study. Mean age was 44 (27-79) and 81 years-old (80-94), for younger and elderly group, respectively. Elderly patients had higher ASA scores (≥ 3) (28.6% vs 75.8%; p = 0.0001) and Charlson comorbidity index (1.99 vs 7.86; p = 0.0001), more diabetes (p = 0.006) and respiratory comorbidities (p = 0.002). No statistical difference was found between two groups in stone size (p = 0.614) and number (p = 0.152). Operative time (74.48 vs 102.96 min; p = 0.0001) and duration of hospitalisation (1.7 vs 2.9 days; p = 0.001) were longer for the elderly. Intraoperative complication rate did not show differences between the two groups (p = 0.166). Postoperative complications rates were similar between the cohorts (7.7% vs 9.5%; p = 0.682). The success rates were 67.5% in the younger group and 71.4% in the elderly group (p = 0.584). No difference was seen in stone recurrence (p = 0.73). A higher rate of visits to the emergency department was found in younger cohort (23.6% vs 11.6%; p = 0.046), mostly duo to stent-related symptoms. CONCLUSIONS: Despite the higher rate of comorbidity in the elderly group, RIRS was a safe procedure with similar complication rate and outcomes at an expense of higher operative time and hospital stay.
