[Microplastics : a silent threat for your kidneys ?].

The production of plastics is steadily increasing and raises major environmental and public health concerns. Those used every day, including in the medical sector, lead to the formation of microplastics (MP). These can then contaminate water, air, soil and our food. Through inhalation or ingestion, MP can enter the bloodstream and reach various organs. The presence of MP has also been demonstrated in the kidneys and urine. In vitro and animal studies suggest potential nephrotoxicity of MP. Patients with kidney diseases may be at increased risk due to higher exposure through medical procedures and reduced urinary elimination. Further studies are needed to clarify this risk.
