A Case of Bifid Phallus and Bladder Neck Incompetence: Is This a Variant of Epispadias or Hypospadias?

Diphallia or duplication of the penis is an extremely rare congenital anomaly. Based on the presence of one or two corpora cavernosa in each of the penises, diphallia is classified into two major groups: bifid phallus and true diphallia. Because true diphallia associated with various anomalies is dominant in published studies, little is known about bifid phallus or isolated cases. Here we present a 9-month-old boy with an isolated bifid phallus. After successful reconstruction of the penis and urethra, urinary incontinence became apparent. To the best of our knowledge, this is the first case of complete bifid phallus associated with bladder neck incompetence.
