Hutch diverticulum

Hutch diverticula are congenital bladder diverticula, seen at the vesicoureteric junction, in the absence of posterior urethral valves or neurogenic bladder. They are though to result from a weakness in the detrusor muscle anterolateral to the ureteral orifice.

The occur almost exclusively in boys with an estimated prevalence of approximately 2% 3.

Urinary tract infection, incontinence, or urinary retention are the most common presentations.

Hutch diverticula are commonly seen with vesicoureteric reflux, because the normal oblique insertion of the ureter is disrupted.

On voiding cystourethrogram, contrast-filled outpouchings from the urinary bladder arise at the vesicoureteric junction. Vesicoureteral reflux is often associated.

Round or oval anechoic fluid collections arising from the base of the urinary bladder or around the ureteric orifice 1.

Incidentally detected diverticula usually do not require any therapy. If associated with reflux, recurrent infection, or obstruction, they should be resected. However because of the risk of the development of carcinoma, some surgeons advocate prophylactic surgery in all cases. Hutch diverticula are prone to spontaneous rupture, as well as post-surgical recurrence.

    • these are transient outpouching normally seen in infants, and represent normal protrusions of urinary bladder into the inguinal rings
    • lateral voiding cystourethrogram usually clarifies the diagnosis
