[The role of the microbiome in urological diseases]

The use of modern molecular technologies in the last decade has given us new insights into the complex interactions of the human microbiome in health and in the pathogenesis of diseases. Among other things, the sterility concept of the urinary tract has been discarded and the goal is now to identify the different microbial signatures associated with various diseases. Dysbalances of the microbiome are increasingly suspected of causing negative effects on various malignant and benign diseases. Recently, such associations have also been shown for prostate carcinoma, renal cell carcinoma and urinary bladder carcinoma. This may lead to the discovery of new potential biomarkers for the diagnosis and as a therapeutic target of the diseases mentioned. For the diagnosis of some benign diseases such as interstitial cystitis, urge incontinence and chronic prostatitis or chronic pelvic pain syndrome, microbial involvement was previously considered an exclusion criterion. However, current studies show that the individual patient's microbiome can have an influence on the development and severity of the respective disease.
