We report two cases of groin herniation of bladder diverticula with different clinical presentation and evolution; bladder diverticula are rarely involved in the pathogenesis of groin hernias. A differential diagnosis is to be made mainly with a common groin hernia. A correct anamnesis, a careful physical examination and a correct diagnostic pattern, including cystography, CT and US scans, are needed. Surgery is recommended when specific symptoms appear, or if an urothelial cancer grows within a diverticulum.
