Video Summary

Non-urothelial bladder cancers are a small subset of bladder cancers that confusingly, often arise from the urothelium. They include cancers like squamous cell carcinomas completely made of squamous cells, and adenocarcinomas entirely consisting of glandular cells. They are believed to arise from chronic irritation of the bladder, especially from an infection by a flatworm called Schistosoma haematobium. People with non-urothelial bladder cancer may present with hematuria, dysuria, urinary urgency and frequency, and weight loss.
