The painless left scrotal mass can be metastasis from RCC to the scrotum (which is rare but several cases have been repoed) or the mass could be varicocele. A secondary varicocele can be caused by compression of the testicular vein by the renal mass (infact RCC is the most common cause of secondary varicocele).
