AB  - Ablative therapy has recently emerged as an option for 
the treatment of small renal masses (SRMs). Benign 
tumors and indolent renal cell carcinoma (RCC) represent 
a majority of these masses, although an additional but 
often unappreciated consideration is upper tract urothelial 
carcinoma (UC). We report the case of a 74-year-old man 
with upper tract UC presenting as a SRM without any 
apparent involvement of the pelvicalyceal system, leading 
to its inadvertent cryoablation. We also discuss the role 
of renal biopsy in the management of SRMs undergoing 
an ablative procedure.
