Bladder diverticula may be congenital or acquired. Most acquired bladder diverticula are associated with longstanding  bladder outlet obstruction and most commonly seen in older men with benign prostatic hypertrophy,  prostatitis], or  prostate cancer. Congenital bladder diverticula are uncommon and occur almost exclusively in boys. Congenital diverticula occur most commonly immediately adjacent to the ureteric orifice: so-called Hutch diverticula. These diverticula most often result in  vesicoureteric reflux.
