Bladder rupture after voiding cystourethrography: A case report and literature review on pitfalls and bladder volume estimation

摘要

Voiding cystourethrography (VCUG) is a common diagnostic study in pediatric urology. Although generally considered a safe procedure, VCUG can incur some complications. Bladder rupture following VCUG is a very rare complication and mostly happens in the setting of unused bladders, previous surgeries, or underlying disease. The rupture is almost always intraperitoneal needing prompt surgical treatment. We present a unique case of extraperitoneal bladder rupture after VCUG in an 8-month-old boy. The rupture remained unnoticed and the patient recovered spontaneously without medical or surgical intervention. To the best of our knowledge, this is the first such case report in the English literature. The information provided may guide clinicians on the proper use of bladder volume formulas in children and also help them in getting a proper VCUG study.
