Vesicoureteral reflux

Patient will present as → a 1-year-old female with a temperature of 103.1 and irritability. A culture of a urine specimen is obtained and shows more than 106 colony-forming units of pansensitive Escherichia coli per milliliter. She is treated with intravenous ampicillin for several days, followed by oral ampicillin, for a total of 14 days of therapy. After the patient no longer had a fever and a urine culture was sterile, voiding cystourethrography was performed while the patient was still receiving ampicillin. The voiding cystourethrogram demonstrates bilateral grade III vesicoureteral reflux, and renal ultrasonography revealed normal findings.

In young female patients, any history that points to recurrent infection, especially cystitis or pyelonephritis, should trigger an evaluation for what?
Vesicoureteral reflux (VUR)

Vesicoureteral reflux (VUR) is a condition in which urine flows retrograde, or backward, from the bladder into the ureters/kidneys

  • In young female patients, any history that points to recurrent infection, especially cystitis or pyelonephritis, should trigger an evaluation for vesicoureteral reflux (VUR)

Diagnose by using voiding cystourethrography (VCUG)

  • Monitor by using serial ultrasonography and VCUGs

Mild to moderate VUR often resolves spontaneously, but the more serious disease may require surgical intervention

  • Children with newly diagnosed VUR are given prophylactic antibiotics depending on their clinical course
  • Antibiotics are administered nightly at half the normal therapeutic dose
Question 1
Which of the following history findings would trigger a workup for vesicoureteral reflux in a young female patient?
A
Dark-colored urine
Hint:
Dark-colored urine and painless hematuria are concerning history findings, but point more toward a renal cause of disease.
B
Epigastric abdominal pain
Hint:
Epigastric abdominal pain is not seen in patients with VUR and any pain associated with VUR, if present, would most likely be located in the renal or suprapubic areas.
C
Nocturnal enuresis
Hint:
Although incontinence can be a sign of cystitis, enuresis limited to night would likely not be present in the presence of infection.
D
Painless hematuria
Hint:
Dark-colored urine and painless hematuria are concerning history findings, but point more toward a renal cause of disease.
E
Recurrent cystitis
Question 1 Explanation: 
Particularly in young female patients, any history that points to recurrent infection, especially cystitis or pyelonephritis, should trigger an evaluation for vesicoureteral reflux (VUR). Dark-colored urine and painless hematuria are concerning history findings, but point more toward a renal cause of disease. Although incontinence can be a sign of cystitis, enuresis limited to night would likely not be present in the presence of infection. Epigastric abdominal pain is not seen in patients with VUR and any pain associated with VUR, if present, would most likely be located in the renal or suprapubic areas.
