How long does the acute phase of a urinary tract infection last?
Patients must not underestimate urinary tract infections (UTIs). If treatment is ineffective, the condition may progress to more serious complications such as cystitis. Patients should maintain good genital hygiene in daily life, avoid unprotected or unhygienic sexual activity, and consume foods that promote diuresis and bowel regularity. With prompt and active treatment, most patients recover within approximately one week.

How long does the acute phase of a urinary tract infection last?
The acute phase of a UTI typically lasts about three days. Patients suspected of having a UTI should promptly consult a urologist for evaluation. A urinalysis can help determine whether white blood cells are present (indicated as “+”), confirming infection. If leukocyturia is detected, antibiotic therapy is indicated. Early administration of sensitive and effective antibiotics during the acute phase yields excellent therapeutic outcomes.
First-line antibiotics include fluoroquinolones—such as levofloxacin (Cravit®)—or cephalosporins—including cefixime and cefdinir. Patients may also take traditional Chinese patent medicines with diuretic and dampness-resolving properties—such as Yinhua Biyan Ling or Relinqing—to alleviate symptoms and support symptomatic management.
With appropriate treatment, most patients with acute UTIs recover within one to two weeks. Currently, numerous effective clinical treatment options are available, including pharmacotherapy, which generally achieves favorable results. During treatment, patients with acute UTIs should rest in bed, minimize prolonged standing or sitting upright, and maintain a relaxed, positive mood—excessive anxiety may exacerbate urinary frequency. Listening to soothing music may help divert attention and reduce anxiety. Adequate fluid intake is essential; patients should drink copious amounts of water daily, especially after sweating.
