Microbiome studies in urology- where do we stand and where can we reach?

The role of microbiome milieu in the urinary tract, their interplay in diverse urological conditions and their therapeutic implications are not completely understood. The microbiome has contributed towards urinary tract infections, urolithiasis and urological cancers. The possibility of manipulating microbiome for diagnosis and treatment is evolving. Probiotics might help in overcoming the problems of recurrent infection and antibiotic resistance. Novel applications like stents and catheters coated with non-pathogenic organisms are being developed. Research in the urinary microbiome has progressed from using mouse models to the presently available three- dimensional cultured organoids, thus making it more feasible. As our knowledge regarding the urinary microbiome increases, justice can be done to many patients in whom the advancements can be used for prophylaxis, diagnosis, treatment and even in improving their quality of life. The growing amount of antibiotic resistance is also a matter of concern and probiotics might be the answer to this upcoming calamity. In this review, we have discussed the role of the urinary microbiome in pathogenesis, diagnosis and treatment of urological conditions and pondered upon its future prospects.
