Abstract:
Objective To discuss the management of urethral duplication in children. Methods The clinical data of 1 8 children(all are males)with urethral duplication were retrospectivelv ana-lyzed. All the 18 patients were sagittal plane included epispadias in 6,hyposPadias in 4 and Y type in the remaining 8. In 6 cases with epispadias,3 patients underwent excision of the accessorv dorsal ure-thra,3 patients without operation.Urethroplasty was necessary in the patient with a duplicated hypo-spadiac urethra. Of 8 patients with Y-type urethral duplication,7 patients underwent 2 stage repair including displacement of the urethra from the anal canal to the perineum at stage 1 and subsequent urethral reconstruction at stage 2.The ventral urethra which was hypospadias had been excised in the other one. Results All the patients were followed-up. Good cosmetic and functional resuIts were a-chieved in the 3 boys who underwent excision of the accessory dorsal urethra.In the hypospadiac du-plication,2 patients could void spontaneously through a normally positioned granular meatus.One boy presented with urethral stenosis after operated. One boy had a vesicostomy for neuropathic bladder. In Y-type urethral duplications,only 1 patient was successful after 2-stage urethroplasty,3 patients de- veloped urethra stricture or fistula,3 boys need the 2-stage operation,the other 0ne who underwent excision of the ventral urethra could void spontaneously. Conclusions Urethral duplication is a rare congenital anomaly.The clinical presentation varies because of the different anatomical Datterns of this abnormality. Commonly the ventral urethra is most functional and maintained after surgical correc-tion.Surgical management should be individual and depend on the anatomical configuration of the du-plicated urethras.
