Successful treatment of a rare Cowper's bulbourethral gland syringocele in an adult with endoscopic laser deroofing using a rigid ureteroscope

Cystic dilatation of Cowper's glands, also known as a syringocele, is a well-known condition of childhood, with increased recognition as a rare presentation of urinary tract symptoms in adults. Surgical techniques for its treatment vary, with several described in the literature. However, consensus on optimal treatment is unclear. We present a rare case of a Cowper's gland syringocele successfully treated with laser deroofing with a previously undescribed method using a rigid ureteroscope, and we also review techniques in the literature. Level of evidence: Level 5.
