Traumatic Urethral Pseudoaneurysm in a 12-Year-Old Boy Leading to Progressive Urethral Stricture and Complete Obstruction: A Case Report and Literature Review.

Urethral pseudoaneurysm is an extremely rare cause of urethrorrhagia in children. Most previously reported pediatric cases required transcatheter arterial embolization and generally resolved without long-term sequelae. We present a 12-year-old boy who sustained blunt perineal trauma and subsequently developed a bulbar urethral pseudoaneurysm requiring two sessions of arterial embolization. Unlike prior reports, the patient developed progressive circumferential urethral stricture leading to complete obstruction five months after initial injury. To our knowledge, this is the first reported pediatric case in which a traumatic urethral pseudoaneurysm resulted in progressive urethral stricture and complete obstruction. The case highlights the importance of long-term follow-up in children with vascular urethral trauma.
