Repeated episodes of urinary tract infections may turn into uremia. Urinary tract infection can be divided into upper urinary tract infection and lower urinary tract infection according to the site of infection, the former is mainly pyelonephritis and the latter is mainly cystitis. Among them, if pyelonephritis is recurrent and prolonged, it progresses to chronic pyelonephritis and may eventually develop into uremia.
Cystitis only affects the bladder and urethra, and patients may experience symptoms such as frequent urination, urgency and painful urination, but usually does not involve the kidneys, affecting kidney function and developing uremia.
Pyelonephritis is an inflammation of the renal pelvis and renal parenchyma caused by pathogenic microorganisms. Patients mainly manifest symptoms such as fever and back pain. Patients with long-term recurrent pyelonephritis may develop chronic pyelonephritis, leading to changes in the parenchymal structure of the kidney and eventually progressing to uremia.
Patients with recurrent urinary tract infections are advised to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
