In 1961, John Hutch described a primary type of bladder diverticula.
The Hutch diverticula are:
- intermittent, usually appear during voiding
- located near the ureterovesical junction
- associated with vesicoureteral reflux
VUR has always to be evaluated both in filling and in voiding.
Ureterocele is a submucosal cystic dilation of the terminal ureter, usually intravesical.
