What to Do for a Urinary Tract Infection After Cesarean Delivery

Following cesarean delivery, women typically experience greater physical weakness than usual. Additionally, an indwelling urinary catheter is often required postoperatively, which 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 resistance, 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, common symptoms 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 urethra, and some individuals may recover spontaneously without medication. However, if fever develops or UTI symptoms become severe, prompt medical evaluation is essential, and antibiotic therapy—prescribed and monitored by a physician—is necessary.

Untreated or inadequately treated UTIs may progress, potentially leading to more serious complications such as pyelonephritis or other upper urinary tract infections. Early intervention—including increased hydration and frequent urination—is strongly recommended, along with close clinical monitoring.
