Duplication or Septation of the Bladder
Complete Duplication of Bladder and Urethra
Bladder duplication is a very rare malformation with 45 reported cases. There are two bladders, each with its own urethra and ureter (Salle, 2000). In addition, there are often duplication anomalies of the external genitalia or the gastrointestinal tract. Treatment may consist in complex reconstruction of the genitourinary tract and aims to protect the upper urinary tract. Due to the rarity of the disease, treatment must be individualized.Incomplete duplication of the Bladder
The duplication of the cranial portion of the bladder leads to a sagittal septum, the trigonum and the singular urethra show no anomalies. Treatment is rarely necessary, possible removal of the smaller portion of the bladder with reimplantation of the ureter.
Further Septation of the Bladder
Transverse septation is also possible.
