| Popis: | Urethral duplication is a rare congenital anomaly, affecting mainly boys. Clinical presentation varies because of the different anatomical patterns of this abnormality. We report our experience in ten males affected by urethral duplication. We retrospectively reviewed the records of ten males affected by urethral duplication. Mild cases of distal type I duplications as well as "Y-type" duplication associated to anorectal malformation were excluded. Evaluation included voiding cystourethrography, retrograde urethrography, intravenous urography and urethrocystoscopy. Mean age at diagnosis was 46.7 +/- 32.3 months A blind ending duplicated urethra (type I) was present in three patients, two urethras originating from a common bladder neck (type II A2) in three, an "Y-type" duplication in three and a complete bladder with incomplete urethral duplication in one. Surgical management included excision of the duplicated urethra in four patients while a displacement of the ventral urethra (in "Y-type" duplication) in perineal-scrotal or scrotal position was performed in two patients as first stage of urethral reconstruction. Good cosmetical and functional results were achieved in all six treated boys while surgical management was not required in four. Urethral duplication is often associated with genito-urinary and gastro-intestinal abnormalities. Embryology is unclear and a lot of hypotheses have been proposed. We believe that the same embryological explanation cannot be applied to all subtypes of urethral duplication. Management must be evaluated for each case. The overall prognosis is good, in spite of the presence of other severe associate congenital anomalies. |
