Prognosis of percutaneous nephrolithotripsy results using specialized evaluation techniques

Background. The efficacy of percutaneous nephrolithotripsy is currently assessed using computed tomography, whose wide implementation in clinical practice is limited by economic reasons and the risk of high radiation doses during the disease monitoring period. Aim. To demonstrate the high predictive precision of nomograms, which are valuable for assessing the expected efficacy of interventions. Materials and methods. Publications devoted to 4 main systems used to assess the expected results of percutaneous nephrolithotripsy - Guy’s, S.T.O.N.E., CROES and S-ReSC - were reviewed. In total, 37publications were analysed. Results. The Guy’s scale for the evaluation of concrements provided 79.6% precision of the evaluation of the clinical effectiveness of percutaneous nephrolithotripsy by the results of the multivariate analysis as an isolated factor. The S.T.O.N.E. index had a 71.6-80% mean summed effectiveness by the studies dedicated to the verification of the S.T.O.N.E. index under 83...
