Long-term Follow-up of Median Raphe Cysts and Parameatal Urethral Cysts in Male Children.

ABSTRACT

OBJECTIVE: To clarify the long-term outcome of median raphe cysts (MRCs) and parameatal urethral cysts (PUCs) in males, the clinical, anatomical, and histological findings of these cysts are described, along with treatment and follow-up. MATERIALS AND METHODS: Forty-six children diagnosed with PUCs and 23 children with MRCs at our institute during the past 14 years were retrospectively reviewed. The indications for surgery were symptoms or family preference. Telephone interviews of the parents or patients were conducted to ascertain the current condition of the cyst at a median age of 12.2 years. Fifty-nine children (85.5%) agreed to the telephone interview. RESULTS: Median age at first presentation was 41 months; 81% of children were asymptomatic. The main symptoms were voiding symptoms with PUCs and pain of the ruptured cyst in MRCs. A total of 41 (59%) children underwent complete excision at a median age of 58 months. No recurrences were encountered with surgery in all children. Of 28 children managed nonoperatively, 22 agreed to an interview. All children (95.5%), except for 1, remained free of symptoms. Six cysts showed spontaneous resolution at a median age of 24 months, and 15 improved or stabilized. No one was concerned about the genital appearance and opted for surgical intervention. CONCLUSION: Complete excision of the cyst is a durable procedure without recurrences in childhood. In the nonoperative management, several cysts may continue to be free of symptoms during childhood, and some cysts may resolve spontaneously during the first 2 years.
