The European Hernia Society classification applied to the rare cases of parastomal hernia after ileal conduit urinary diversion: a retrospective cohort of 96 patients.

Hernia after ileal conduit is common with radiographic rates approaching 30% at two years, with obesity being an independent risk factor. The relationship between prior tobacco use and a lower hernia rate may be limited to this study but presents an opportunity for future investigation. No difference in PH rates were observed between open and minimally invasive surgery and between intracorporeal and extracorporeal conduits.
