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.
Round or oval anechoic fluid collections arising from the base of the urinary bladder or around the ureteric orifice 1.
Treatment and prognosis
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.
- "bladder ears"
- 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
