Abstract
Abstract Objective Compare the outcomes of RIRS and PCNL for the treatment of 1 to 2 cm lower calyceal renal calculi regarding the stone free rate, operative time, fluoroscopy time, hospital stay and complication rate. Materials and Methods Patients with a single lower calyceal stone with an evidence of a CT diameter between 1 and 2 cm were enrolled in this randomized study. Patients were randomized into two groups: group 1: underwent RIRS (20pts); group 2: underwent PCNL (20 pts). Patients were evaluated with KUB and CT after one month. Results Mean fluoroscopy times and Hospital stay were significantly greater in the PCNL group than in RIRS group, In the RIRS group, the stone-free rate was 85% (17/20 patients); this rate increased to 95% after a second intervention. After a single PCNL procedure, 19 of 20 (95%) patients were completely stone free and For complications, there were minimal differences in both procedures, except for hemorrhage three patients who were treated with PCNL need blood transfusion Conclusions PCNL and RIRS are safe and effective methods for medium-sized LP calculi. For selected patients, RIRS may represent an alternative therapy to PCNL, with acceptable efficacy and low morbidity., RIRS compared to PCNL offers the best outcome in terms of radiation exposure and hospital stay.
