Imaging Studies VI: Voiding Cystourethrography and Cystography

2.6K
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

371
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Urologic Endoscopic Procedure: Cystoscopic Examination

4.1K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Urinary Tract Infection II: Pathophysiology

906
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Imaging Studies III: Computed Tomography

492
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

2.0K
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Summary
This summary is machine-generated.

The risk of post-procedural urinary tract infection (ppUTI) after a cystogram is very low, at 1.0%. Children with pre-existing urologic diagnoses, such as VUR, are at highest risk for ppUTI.

Area of Science:

  • Pediatric Urology
  • Diagnostic Imaging
  • Infectious Disease

Background:

  • Post-procedural urinary tract infection (ppUTI) rates after voiding cystourethrogram (VCUG) vary widely.
  • Determining the precise risk and predictors of ppUTI after cystograms is crucial for patient care.

Purpose of the Study:

  • To ascertain the incidence of symptomatic ppUTI following cystogram procedures.
  • To identify risk factors associated with ppUTI in pediatric patients.

Main Methods:

  • Retrospective cohort study involving children undergoing VCUG or radionuclide cystogram.
  • Exclusion of patients with neurogenic bladder or incomplete follow-up.
  • Symptomatic ppUTI within 7 days post-procedure was the primary outcome measure.

Main Results:

  • A total of 1203 cystograms were analyzed in 1108 children.
  • The overall incidence of ppUTI was low at 1.0% (12 cases).
  • Pre-existing urologic diagnosis (e.g., VUR, hydronephrosis) and abnormal cystogram findings were significant predictors of ppUTI.

Conclusions:

  • The risk of ppUTI after cystogram is minimal, with a 1.0% incidence in this cohort.
  • Children with pre-existing urologic conditions, particularly moderate to high-grade VUR, face the highest risk.
  • Peri-procedural antibiotic prophylaxis is not recommended solely for ppUTI prevention in these procedures.
