Abstract
In the 4th to 6th week of gestation, the folds of Rathke grow in from the lateral aspects to divide the cloaca into the urogenital canal anteriorly and an anorectal canal posteriorly. The upper portion of the urogenital canal begins to form the bladder, within which the urothelium induces the surrounding pelvic mesenchyme to differentiate and form the detrusor muscle. The urachus connects the adult bladder to the anterior abdominal wall, and this normally closes in utero, but continued patency may relate to infravesical obstruction.
