Symptoms of chronic pyelonephritis in women vary from person to person, and different patients show different symptoms. The clinical manifestations of chronic pyelonephritis are complicated, and common manifestations include low-grade fever of varying degrees, intermittent urinary frequency, discomfort in urination, lumbar pain, and impaired renal tubular function. Chronic pyelonephritis refers to inflammation of the renal pelvis and renal parenchyma, and belongs to a type of upper urinary tract infection, which is mostly caused by bacterial infection, often accompanied by inflammation of the lower urinary tract. Its clinical manifestations are more complex, systemic and localized urinary manifestations are atypical, sometimes only manifested as asymptomatic bacteriuria. More than half of the patients may have a history of acute pyelonephritis, followed by varying degrees of low-grade fever, intermittent urinary frequency, urinary discomfort, lumbar pain, and impaired renal tubular function, such as nocturia, hypogranulonephrosis, etc. The disease may progress to chronic nephritis. Persistent disease can develop into chronic renal failure. If female patients find chronic pyelonephritis, it is recommended to go to regular hospitals in time and standardize the treatment under the guidance of doctors.
