Which histologic subtype of cancer is associated with stones in the bladder?
Less than 5% of bladder cancers in the United States are squamous cell carcinomas (SCCs). However, worldwide, SCC is the most common form, accounting for 75% of bladder cancer in underdeveloped nations. In the United States, SCC is associated with persistent inflammation from long-term indwelling Foley catheters and bladder stones. In underdeveloped nations, SCC is associated with bladder infection by Schistosoma haematobium.
