What to Do for a Urinary Tract Infection After Cesarean Delivery

Following cesarean delivery, women often experience increased physical weakness compared to their normal state. Additionally, an indwelling urinary catheter is typically required postoperatively; insertion of the catheter may cause minor trauma to the urethral mucosa. Such mucosal injury compromises local defense mechanisms, rendering the urinary tract more susceptible to bacterial invasion and subsequent infection. Similarly, the surgical trauma associated with cesarean delivery leads to a generalized decline in immune function, further increasing infection risk. Moreover, postpartum lochia—containing blood—provides an ideal medium for bacterial growth, thereby facilitating infection. Once a urinary tract infection (UTI) develops, symptoms may include urinary frequency, urgency, a burning sensation during urination, and lower abdominal discomfort.

If UTI symptoms are mild or if no fever is present, specific antimicrobial therapy is generally not required at this stage. Instead, patients should increase fluid intake significantly; frequent urination helps flush bacteria from the urinary tract, and some individuals may recover spontaneously without pharmacologic intervention. However, if fever develops or UTI symptoms become severe, prompt medical evaluation is essential, and antibiotic therapy should be initiated under physician guidance.

Without timely treatment, the infection may worsen and potentially progress to upper urinary tract infections such as pyelonephritis. Early intervention—including increased hydration and frequent voiding—is strongly recommended, along with close clinical monitoring.
