Evaluation of the efficacy of multiple-access endoscopic surgery for staghorn and multiple nephrolithiasis

Background. Despite of recent advances in the development of endoscopic treatment for staghorn nephrolithiasis, stone-free rates after percutaneous nephrolithotomy (PNL), still remaining lower comparing to other types of renal stones. Multiple access approach of percutaneous surgery for renal stones thus may be another cost-effective procedure. Patients and methods. Data of 30 patients underwent multiple-access PNL due to staghorn and multiple nephrolithiasis was investigated. Mean age of patients was 29.3±11.9 years. We evaluated duration of the intervention, stone free rate, duration of hospital stay, rate and severity of peri- and postoperative complications, etc. Comparative analysis was performed using Student’s t and Fisher exact tests. Strength of associations was assessed using Spearman’s rank correlation coefficient (rho). Value of р
