In some patient categories, organ-sparing surgeries are possible if several criteria are met. According to scientific publications, tumor recurrence and progression rates significantly vary in non-radical surgical treatment, and outcomes are contradictory. The article presents a clinical case of organ-sparing treatment of a young patient with progressive urothelial carcinoma.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящее время основным способом лечения злокачественных опухолей лоханок почек остается радикальная нефруретерэктомия.
