Misdiagnosis of hematuria after catheterization: A case report and literature review of posterior urethral hemangioma in a pediatric male.

Hemangioma is a common benign skin tumor, but it is relatively rare in the bladder, prostate, and urethra. We report a case of a 12-year-old male child who was misdiagnosed in the early stage due to hematuria after catheterization. Due to severe gross hematuria, he was re-admitted for further examination, which confirmed the diagnosis of urethral hemangioma. Successful treatment was achieved through local cauterization and pingyangmycin injection under cystoscopy. This case highlights the importance of considering urethral hemangioma in similar scenarios, providing valuable insights for doctors and urging further research on this underdiagnosed condition.
