OBJECTIVE: To determine whether Charlson comorbidity index (CCI) predicts the postoperative complications after percutaneous nephrolithotomy (PCNL) and could be a plausible option to avoid surgery and its potential risks in elderly patients with significant comorbidites. METHODS: The data from 283 elderly patients (age ≥ 60 years) who underwent PCNL in 4 large referral hospitals were reviewed in the present multicenter study. For each patient, we evaluated pre-existing comorbidities and calculated the CCI score. The patients were classified to 3 CCI score categories (0, 1, ≥ 2) and compared regarding the stone-free and complications rates. RESULTS: The mean patient age was 64.7, 65.6, and 67.7 years in the 3 groups. The stone-free rate after primary PCNL was 85.7% in group 1, 86.1% in group 2, and 75.0% in group 3. These rates increased to 90.8%, 95.4%, and 83.9% after a second intervention (P = .049). The overall postoperative complication rate was 38.8%. The most common complication was hemorrhage necessitating blood transfusion in 34 patients (12%), and we found an increased risk of hemorrhage associated with the CCI score (P = .011). Life-threatening medical complications developed in 7.6% of the patients in group 1, 12% of the patients in group 2, and 28.6% of the patients in group 3 (P = .001). A multivariate logistic regression analysis showed that a high CCI score, bleeding, and operative time had significant influence on the postoperative medical complication in this population. CONCLUSION: Conservative management of asymptomatic large kidney stones appears to be a safe alternative to PCNL in elderly patients with significant comorbidites.
