The major cause of pediatric anterior urethral injuries (AUIs) is blunt trauma.1 2 Penetrating injuries caused by explosive trauma are rare in pediatric patients. Both early and delayed urethral repairs are optional strategies to manage AUIs. Studies from clinical management of blunt trauma have concluded rich experiences. However, poor experiences can be used to manage explosive AUIs. In this case, a 7-year-old boy threw a detonator into the fire. His external genitalia and bilateral medial region of the thigh were injured in a sudden explosion. Corpus spongiosum penis was covered by incomplete prepuce. Splintered glans penis with high-degree edema concealed the urethral meatus. The swollen testis was detected in the tattered scrotum. Muscular layer was included in explosive injuries of the bilateral thigh (figure 1). Surgical debridement was performed urgently. It was difficult to identify the external urethral orifice in the seriously damaged penis with progressive edema. Cystoscopy and urethral catheter insertion were abandoned. Open suprapubic cystostomy was performed. On day 5, reduced edema of the impaired penis made it possible to identify urethral meatus. Application of cystoscopy discovered a small laceration of the urethral meatus. The posterior urethra and neck of the bladder were normal. Simple urethral closure was done to repair the laceration and a urinary catheter was installed. The residual defect of the prepuce was repaired by the scrotal septum free graft urethroplasty, and urinary diversion ended on day 12 (figure 2). Application of urgent suprapubic diversion then delayed exploration and repair at the fifth day of AUI reduced the risk of urethral trauma-related complications. No urinary fistula or urethral trauma-related complications were observed within 1 year of follow-up. Pediatric blast AUIs lead to serious tissue damages and high-degree edema. Urgent urethral exploration may increase the risk of secondary injuries. Urine diversion is a priority step for early management. Swelling degradation of the injured urethra is a better timing resolution.
