Urinary tract infections complicating pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Urology

Background:

• Urinary tract infections (UTIs), ranging from asymptomatic bacteriuria to severe pyelonephritis, frequently complicate pregnancy.
• Untreated asymptomatic bacteriuria can lead to serious infections in a significant percentage of cases.
• Routine screening for bacteriuria is advisable in high-risk pregnant populations, especially those from lower socioeconomic backgrounds.

Purpose of the Study:

• To review the spectrum of urinary infections in pregnancy.
• To discuss the implications of asymptomatic bacteriuria and acute cystitis.
• To outline management strategies for pyelonephritis in pregnant individuals.

Main Methods:

• Literature review of urinary infections in pregnancy.
• Analysis of treatment outcomes and complications.
• Discussion of diagnostic and therapeutic recommendations.

Main Results:

• Asymptomatic bacteriuria recurs in one-third of treated women, with a persistent 25% risk of pyelonephritis.
• Acute cystitis requires careful management to avoid misdiagnosis of early pyelonephritis, precluding single-dose therapy.
• Pyelonephritis, the most common severe bacterial infection in pregnancy, often requires hospitalization and intravenous treatment.
• Prompt identification of obstruction is crucial for persistent fever or sepsis after 48 hours of treatment.
• Severe pyelonephritis complications include septic shock, renal dysfunction, hemolysis, thrombocytopenia, and pulmonary capillary injury in approximately 20% of cases.

Conclusions:

• Screening for asymptomatic bacteriuria in high-risk pregnant individuals is clinically justified.
• Appropriate antimicrobial therapy and supportive care are essential for managing UTIs in pregnancy.
• Vigilance for complications and underlying obstruction is critical in cases of severe pyelonephritis.
