UTI is a type of urinary tract infection that can cause pyelonephritis, but is not associated with glomerulonephritis.
UTI is an inflammatory response caused by infection by various pathogens, such as various bacteria, viruses, fungi, and mycoplasma. If left untreated, urethritis can lead to the infection spreading upward, resulting in bladder, ureter, and even renal pelvis infections, leading to acute and chronic pyelonephritis, known as an upwardly mobile infection, which accounts for about 95% of all urinary tract infections.
Nephritis usually refers to primary glomerular disease, including acute glomerulonephritis, chronic glomerulonephritis, and acute progressive glomerulonephritis, etc. The pathogenesis has not been fully clarified yet, and most of them are caused by inflammatory injury mediated by immune response, which has nothing to do with UTI.
Patients suffering from nephritis or urethritis are advised to go to the hospital as soon as possible and receive targeted treatment under the guidance of professional doctors.
