[Bladder hernia: report of a case series and review of the literature].

Inguinal bladder hernia accounts for only 1 - 4 % of all inguinal hernias. It may be difficult to diagnose due to the atypical symptoms. In most cases, the diagnosis is only made intraoperatively. However, a preoperative diagnosis is important to avoid possible iatrogenic complications. We report a case series of five patients with the rare pathology of bladder hernia treated in our department in the past 20 years.
