Recurrent urinary tract infections are not necessarily renal tuberculosis, and those who still have symptoms after anti-infective treatment should consider the possibility of renal tuberculosis. Recurrent urinary tract infections are prevalent in women, diabetics, and immunocompromised people, manifested by recurrent urinary frequency, urinary urgency, urinary pain, urine routine commonly leukocyturia, erythrocyturia, and positive urine bacterial culture. Treatment should identify the causes, such as insufficient antibiotic course, resistance to current antibiotics, stone obstruction, poor urination, etc. Antibiotics are selected according to urine culture drug sensitivity. In addition to the symptoms of urinary frequency, urgency and pain, renal tuberculosis may be accompanied by low-grade fever and emaciation, etc. In the case of renal tuberculosis, antacid bacilli can usually be found in the urinary sediment, and there may be some specific manifestations on CT, and anti-infective treatment is ineffective. Those who have recurrent urinary tract infections are advised to go to a regular hospital for diagnosis and treatment plan after evaluation by a specialist. If renal tuberculosis is suspected, urinary tubercle bacillus culture, urinary tract CT and other related examinations should be performed for active treatment.
