Spontaneous rupture of a continent cutaneous urinary diversion is uncommon and diagnosis of this situation requires a high degree of suspicion. In this paper we present a 66-year-old man with continent cutaneous pouch after radical cystoprostatectomy that presented with spontaneous perforation 25 years after surgery. Spontaneous pouch perforation in our case after 25 years emphasizes the need for long follow-up in patients with continent diversion.
