Radical cystectomy with ileal conduit urinary diversion serves as a foundational curative treatment strategy for selected patients afflicted with urothelial carcinoma of the bladder. Parastomal hernia after this procedure is an underestimated and undertreated clinical entity, which heavily impairs patients' quality of life due to symptoms of pain, leakage, application or skin problems. There is little evidence about prophylactic mesh placement for parastomal hernia prevention. In this study we examine the use of meshes during radical cystectomy and compare them with a control group.
