Recurrent urinary tract infections are classified as recurrence and reinfection, which means that you have had a previous urinary tract infection and have contracted another one 2 weeks after it has healed. If the infection is the same as the last one, it is called a recurrence. If the bacteria is different from last time, it is called a new infection, which is called a recurrent urinary tract infection, that is, the last infection is cured, and then 2 weeks later, it is called a recurrent urinary tract infection. Recurrent urinary tract infections are usually seen in patients who are in poor health or bedridden for a long time, or in patients with urinary tract deformities or obstructions, such as congenital deformities or stones, which can obstruct the urinary tract and make it not particularly open, causing recurrent infections. There are also patients with diabetes, for example, who have high blood sugar and poor blood sugar control, and whose bodies are a good culture medium for bacteria, which is also prone to recurrent infections.
