This case report is about a 4-year-old patient with a IIA2 “Y-type” duplication, with the accessory urethra arising from the anterior orthotopic urethra and exiting in perineal-scrotal position, in association with posterior urethral valves (PUV). Cystourethroscopy through the ventral urethra revealed a type III urethral valve (diaphragm) and this was fulgurated. Duplicated dorsal urethra was excised surgically. Postoperative period was uneventful. This case is unique, because it shows PUV in a child with a very rare type of “Y-type” duplication. The presence of PUV in patients with urethral duplication is probably not an incidental finding but, to date, embryology of this rare association is not known.
