Acute pyelonephritis in pregnancy: an anterospective study

Area of Science:

• Obstetrics and Gynecology
• Nephrology
• Infectious Diseases

Background:

• Acute pyelonephritis affects over 2% of obstetric patients.
• Common symptoms include chills, back pain, fever, and costovertebral angle tenderness.

Purpose of the Study:

• To investigate the incidence, clinical presentation, and outcomes of acute pyelonephritis in obstetric patients.
• To assess the rate of recurrent urinary tract infections and renal dysfunction.

Main Methods:

• Retrospective analysis of 24,000 obstetric patients over 4.5 years.
• Clinical data collection, including presenting complaints, urinalysis, and renal function tests.
• Long-term follow-up (8-13 years) for recurrence and subsequent infections.

Main Results:

• 656 women were admitted for acute pyelonephritis.
• 21% of tested women showed transient renal dysfunction.
• 23% of women with antepartum pyelonephritis experienced recurrence, with half occurring antepartum.
• 42% of women treated for symptomatic urinary infections when not pregnant.
• 38% of women in subsequent pregnancies had urinary infections (29% pyelonephritis, 9% asymptomatic bacteriuria/cystitis).

Conclusions:

• Antepartum pyelonephritis is a significant concern in obstetric patients.
• Recurrent urinary tract infections are common, necessitating long-term monitoring and management.
• Prompt diagnosis and management are crucial to prevent renal dysfunction and recurrent infections.
