Prerequisites for lithogenesis after radical cystectomy: literature review; [Предпосылки к литогенезу после радикальной цистэктомии: обзор литературы]

Recently, there has been a worldwide increase in the incidence of bladder cancer. Improved morphological diagnostics, increased surgical activity and availability of chemotherapy allowed reducing the one-year mortality rate and increasing the five-year survival rate. However, at the same time, there was a struggle with complications arising after the treatment. According to the world and domestic literature, it is noted that with an increase in life expectancy in patients who underwent radical cystectomy with intestinal urine derivation, an almost twofold increase in the frequency of complications, including the formation of urinary stones, is recorded. Previous studies have shown that about 60 % of the stones identified in this category of patients are infectious, and 40 % formed because of metabolic disorders, which have their own characteristics with different types of urine derivation. In this work, we present an overview of the predisposition for stone formation in patients who underwent cystectomy for musculoinvasive bladder cancer, taking into account the type of urine derivation. © 2022 ABC-press Publishing House.
