Overview

Ultrasound

  • Ultrasound has a limited role to play in either diagnosis or staging transitional cell carcinomas of the urinary tract in general.
  • On ultrasound examination transitional cell carcinomas appear as solid, albeit hypoechoic masses located within the the renal pelvis or within a dilated calyx (also known as an oncocalyx).[1]
  • In patients in whom ultrasound is technically difficult care must be taken to not interpret the hypoechoic mass as hydronephrosis.
  • Rarely TCCs with squamous metaplasia and abundant keratin formation appear echogenic and densely shadowing and may mimic a renal calculus.
