Abstract
We analyzed the treatment of 1952 patients with urolithiasis, who had undergone 2223 percutaneous nephrolithotomy. In our study, complications of percutaneous nephrolithotomy were observed in 507 cases, accounting 22.8 %. All complications were distributed under a modifi ed Clavien-Dindo scale. Among all complications side effects of Ist and IInd group by Clavien classifi cation (69.3 % cases) dominated. Postoperative mortality of patients after percutaneous nephrolithotomy – 0.13 % cases. For evaluation of the utility of the Guy’s stone score in prediction of PCNL complications we compared the frequencies of complications depending on the GSS of patients. Among all 507 complicated cases in 46 (9.1 %) pts renal calculi were characterized by GSS-1, in 87(17.2 %) pts – GSS-2, in 213(42.0 %) pts – GSS-3, in 161(31.8 %) pts – GSS-4. In major part of complicated cases were diagnosed renal calculi with GSS-3 grade while severe complications (Сlavien-Dindo ІІІ-V) predominantly were registered in patients with GSS 3-4 kidney stones. The Guy’s stone score 3–4 could be considered a prognostic factor of PCNL complications development in patients with kidney stones.
