Abstract

The widespread introduction of percutaneous nephrolithotomy has led to a significant narrowing of the traditional indications for surgery for staghorn calculi. We analyzed the efficacy and safety of percutaneous nephrolithotomy, depending on the stage ofstaghorn nephrolithiasis. In a period of 2008-2011, 120 patients with staghorn calculus underwent percutaneous nephrolithotomy. Data from spiral computed tomography were used in planning the surgical approach. In the preoperative period, staghorn calculi SN1-SN2 were diagnosed in 31.7% of patients (Group 1), and complex forms of stones corresponding SH3-SN4--in 68,3% (Group 2). The between-group analysis showed that the average time of surgery was significantly (p < 0,01) higher in patients in Group 2, the same group reported more frequent blood loss requiring to stop operation, as well as hyperthermia, hypotension during surgery, but the difference was not significant compared to Group 1 (p > 0,05). Conversion to open surgery was required in 2,6 and 2,7% of patients in Group 1 and Group 2, respectively. Application of PNL allowed to completely remove SN1-SN2 calculi in 94,7% of cases in Group 1, but similar result was achieved only in 63.4% of cases in most difficult group of patients with SN3-SN4.
