The aim of this paper is to show and point out the number, variety, advantages and disadvantages of radiological methods of examination in kidney diagnostics. The material and method of work is the experience gained in the profession based on urographic examinations and other radiological methods of examination of the urogenital system, primarily in 18,000 IVUs performed in the period 1994-2021. at the Center for Radiology of the University Medical Center Nis and numerous literal announcements of authors and co-authors written in domestic and foreign journals.

Abstract – Modern Bosnia and Herzegovina is a state consisting of multiple ethnicities and regions located in the Western Balkan, with a very complex history. The earliest historical findings show that its area was inhabited since the Paleolithic. From that time, this part of Europe, especially the region of the Modern Bosnia and Herzegovina, could be recognized as the crossroad for the different human migration and the meeting point for different cultures, religions and gene pools. Mitochondrial DNA is being used for maternal lineage testing, while the Y chromosome is being used for paternal lineage testing. Therefore, these markers are being referred to as lineage markers. Lineage markers are often used for parental lineage monitoring in population genetics, human genetics, as well as in forensic genetics. The main intention of this paper is to construct a short overview of the Y chromosome studies performed in Bosnia and Herzegovina within the last two decades.
