Urography in children: when should it be done? 2. Conditions other than infection

Area of Science:

• Pediatric Radiology
• Urology
• Medical Imaging

Background:

• Renal anomalies are associated with conditions like imperforate anus, vertebral abnormalities, and Fanconi anemia.
• Urinary problems can develop later in life in conditions such as myelodysplasia, prune-belly syndrome, and bladder exstrophy.
• Patients with urinary diversion require monitoring for complications like hydronephrosis and obstruction.

Purpose of the Study:

• To outline the indications for excretory urography in pediatric patients.
• To clarify when urography is not indicated for suspected urinary abnormalities.
• To emphasize the diagnostic value of urography in specific congenital and acquired conditions.

Main Methods:

• Review of clinical scenarios and associated diagnostic imaging protocols.
• Analysis of conditions requiring baseline or follow-up urography.
• Identification of absolute contraindications for urography.

Main Results:

• Excretory urography is indicated for congenital anomalies (imperforate anus, vertebral defects, Fanconi anemia), myelodysplasia, prune-belly syndrome, and bladder exstrophy.
• Immediate urography is warranted for signs such as dribbling, hematuria, neonatal pneumothorax/pneumomediastinum, or abdominal mass.
• Urography is generally not required for hypospadias, isolated ear deformities, or undescended testes.
• Dehydration is the sole absolute contraindication to performing urography.

Conclusions:

• Excretory urography is a valuable tool for diagnosing and monitoring renal and urinary tract abnormalities in specific pediatric populations.
• Clinical presentation and associated conditions are key factors in determining the need for urography.
• Careful patient selection ensures optimal use of urography, avoiding unnecessary procedures and recognizing its limitations.
