[Appendico vesical fistula (author's transl)].

Appendico vesical fistula is an uncommon clinical entity which concerns not only the general and urological surgeons but also the general practitioner. It develops as a complication of untreated appendicitis and may go unrecognized for many years. The chief clinical feature is recurrent episodes of acute cystitis. It may occur at any age but usually in the younger group. The frequent absence of pneumaturia and fecaluria helps to distinguish it from other variants of entero-vesical fistula. Appendectomy and excision of the fistula are usually followed by complete recovery.
