Abstract

Objective: This study aims to evaluate the results of percutaneous nephrolithotomy (PCNL) for the treatment of renal stones larger than 2cm. Subject and method: A prospective study carried out on 139 patients with renal stones larger than 2cm treated by percutaneous nephrolithotomy (PCNL) from December 2009 to December 2016 at 108 Military Central Hospital. Result: Among 139 patients studied, the mean age of patients was: 50.6 ± 10.7 years. The mean stone size was 3.97 ± 1.46cm. The mean operative time was 107.8 ± 31.1 minutes. The PCNL procedure was successfully completed in all patients. The success rate (stone-free status) was 77% (107/139). The mean post-operative hospital stay was 6.2 ± 2.7 days. The overall complications were observed in 22.3% of cases (31/139). According to the Clavien-Dindo classification: Grade 1 (12.9%), grade 2 (7.2%), grade 3 (2.8%), grade 4 (0.7%), grade 5 (0%). Conclusion: PCNL is a minimally invasive, safe and effective choice of treatment for renal stone larger than 2cm with high success rate.
