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.
ABSTRACT
The use of a gracilis myocutaneous flap to overlay an extensively traumatized scrotoperineal soft tissue defect, through which both testes and the ruptured bulbous urethra were exposed, is discussed. The transplanted gracilis myocutaneous flap, which included vascularized and innervated tissue, was well taken and covered the perineal defect, exposed testes and urethral stricture both cosmetically and functionally.
