About This Course

Urinary tract infection (UTI) is a common presentation in urgent care. UTIs are categorized based on whether the upper or lower urinary tract is involved, and also as uncomplicated versus complicated. The urgent care clinician must carefully categorize the infection for appropriate management. A working knowledge of local antibiograms or at least national susceptibility patterns of the most likely pathogens is essential in treating UTI, and utilization of an antibiotic stewardship program is ideal. Certain patient populations require variations in management, including pregnant patients. This issue of Evidence-Based Urgent Care reviews the evidence to answer these key questions for the patient who presents to urgent care with a possible UTI:

Is this an upper or lower UTI?

Is this UTI uncomplicated or complicated?

Which antibiotic is appropriate to treat this patient?

Is there an anatomic or functional abnormality or other concern that would warrant imaging?

Is this a UTI mimic? Could this potentially be a more dangerous condition, or could the patient be septic?

Is this patient best treated as an outpatient, or is ED transfer for more exhaustive workup/treatment indicated?

Case Presentations

CASE 1
A 21-year-old woman presents to UC with dysuria…
  • She describes 3 days of dysuria and urgency. She also reports mild suprapubic pain.
  • Before prescribing antibiotics, you decide to ask the patient if she is experiencing any gynecologic symptoms...
CASE 2
A 38-year-old woman presents to UC with a persistent fever after a recent UTI, despite being on her second course of antibiotics…
  • She complains of nagging left-sided back pain.
  • The patient is afebrile after taking ibuprofen prior to arrival. She is well appearing and her vital signs are normal except for slight tachycardia. Her history includes kidney stones and a tubal ligation.
  • You consider antibiotic resistance, but wonder if there is more going on here…
CASE 3
A 23-year-old woman arrives in the UC clinic with fever, left flank pain, and recent dysuria...
  • The patient denies any previous medical problems and has no other complaints.
  • She is afebrile and her heart rate is 90 beats/min.
  • She has slight costovertebral angle tenderness on the left.
  • You suspect UTI, but wonder if you should have concern for something else…

Introduction

Urinary tract infections (UTIs) represent a heterogeneous group of disorders involving infection of all or part of the urinary tract. In the United States, UTIs result in more than 10 million outpatient healthcare encounters and approximately 1 million emergency department (ED) visits each year.1 Females are much more commonly affected than males. While the diagnosis and treatment of UTIs may seem like routine tasks for urgent care (UC) clinicians, effective management of the full spectrum of urinary tract conditions and their mimics presents a variety of challenges. Proper management of UTIs will decrease treatment failures, bouncebacks, and complications. By being familiar with atypical presentations and knowing when more extensive workup is indicated, clinicians can optimize outcomes and minimize errors in the management of UTI.

UTIs are divided into those involving the lower tract and those involving the upper tract. Lower tract infection is confined primarily to the urinary bladder and is termed cystitis. Infection of the upper urinary tract is termed pyelonephritis and indicates involvement of the kidney and ureter. Pyelonephritis is characteristically more severe than cystitis, and patients with pyelonephritis frequently have systemic symptoms and appear more ill.

UTIs are also classified as uncomplicated versus complicated. This classification is not specifically anatomic or physiologic, but more generally attempts to discern which patients are most likely to recover uneventfully with therapy (uncomplicated) versus patients who are at an increased risk of treatment failure (complicated). Patient comorbidities are the primary determinants of whether a UTI is complicated versus uncomplicated.2

The frequency and relatively benign course of most UTIs may lull UC clinicians into the false perception that these are always simple cases. While most UTIs are straightforward to diagnose, patient comorbidities, local bacterial susceptibility patterns, and available antibiotic choices and costs must be considered to ensure an optimal outcome.
