Abstract

Introduction and importance: Parameatal urethral cyst is a rare benign congenital urethral disorder with limited reports in the literature. The formation of the cyst is believed due to the obstruction of the paraurethral duct. This disorder usually does not produce symptoms even though, in an advanced case, urinary retention and flow disturbance may occur.

Case presentation: Herewith, we report case series of parameatal urethral cysts in 5, 11, and 17 years old boys treated with complete surgical cyst excision. The first was 11 years-old-boy with asymptomatic 7 mm swelling in his urethral meatus. The second case was a 5 years-old-boy with 5 mm swelling in his urethral meatus with the complaint of urinary stream distortion. The third case involved a 17-year-old adolescent with a 4 mm cystic bulge in his urethral meatus that caused urinary distortion.

Clinical discussions: In these cases, the cysts were completely removed with surgical excision and the patients underwent circumcision. Histological examination revealed a cyst wall lined with squamous and columnar epithelium. Good cosmetic result without any recurrent mass and voiding difficulties was reported after 2 weeks of follow-up.

Conclusions: This study reported three cases of parameatal urethral cysts late presentation at an older age due to no prior symptoms. The patients were managed with surgical excision of the cyst resulting in good cosmesis outcome and without recurrence.
