The article presents the analysis of published data (Scopus, Web of Science, PubMed/MedLine, The Cochrane Library, and eLIBRARY databases) devoted to the study of existing criteria for assessment of pyeloplasty effectiveness. Published sources most often refer to the dynamics of reduction of the renal collecting system (RCS) and postoperative renal functional status as the assessment criteria. However, there are no consistent values, which could be employed as assessment criteria indicating success as soon as they are registered. The tools used to estimate RCS reduction are not standardized in terms of research techniques, projection of RCS dilatation measurement, and the locations between which renal and pelvic anatomic structures are measured. A variety of approaches to measuring the anteroposterior renal pelvis dimension in children with hydronephrosis tends to blur the analysis of actual pyeloplasty results. This review of published sources demonstrates the lack of agreement as regards the criteria for assessment of pyeloplasty effectiveness. There is a pressing need for appropriate steps to harmonize ultrasonography methods, to standardize the anatomic landmarks for measurement, and to define the criteria to be used to assess the effectiveness of pyeloplasty.
