Abstract

Objectives: In this study, we aimed to compare the outcomes and complication rates of percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) in geriatric patients according to Charlson comorbidity index (CCI). Materials and Methods: Between April 2011 and January 2020, patients who underwent PCNL and RIRS for renal stone between 10 and 30 mm in geriatric patients were retrospectively evaluated. All patients’ Pre-surgery comorbidities were recorded and the CCI was calculated. The two groups’ perioperative values, stone free rates and complication rates were compared. Postoperative complications were noted according to the Clavien scoring system. Results: There were 89 and 72 patients in the PCNL and RIRS group, respectively. The median age was 67 years in both of groups (p=0.192). The stone size were 22.2 ± 3.5 and 19.9 ± 7.1 in the PCNL and RIRS group, respec¬tively ( p = 0.082). CCI scores were similar in both groups (p=0.098). Stone free and complication rates were significantly higher in PCNL group (p = 0.021, p = 0.034). Also we found that overall complication and major complication rates were statistically significant difference with especially Charlson comorbidity index score ≥2 in PCNL group (p = 0,016, p = 0,029). According to correlation analysis of intraoperative and postoperative results with Charlson comorbidity index, there was positive correlation between total complication with PCNL and RIRS group, respectively (p < 0,001, p = 0.024). In addition, there was positive correlation between lenght of hospital stay with PCNL and RIRS group, respectively (p = 0,007, p < 0,001). Also there was positive correlation between blood transfusion requirement with PCNL group (p=0,009). Conclusion: Despite there was higher stone clearence in PCNL, the complication rates were higher compared to RIRS. So RIRS might be a safe alternative treatment method to PCNL in older patients with a high CCI score.
