Özet
The objective of our study was to prospectively evaluate the diagnostic performance of strain elastography for differentiation between renal cell carcinomas (RCCs) and transitional cell carcinomas (TCCs) of kidney. A total of 99 consecutive patients who were referred to our hospital because of a newly diagnosed solid renal mass suspicious for malignancy on radiological screenings were evaluated with sonography, including strain elastography. Strain elastography was used to compare the stiffness of the renal masses and renal cortex. The ratio of strain in a renal mass and nearby renal cortex was defined as the strain index value. Mean strain index values for RCCs and TCCs were compared, and mean strain index values between histological subtypes of RCC were also compared. Although TCCs were smaller than RCCs (p < 0.001), there were no significant differences in gender distribution and mean age of the patients, and mean probe-tumor distance between RCC and TCC. The mean strain index value +/- SD for TCC (5.18 +/- 1.12) was significantly higher than the value for RCC (4.04 +/- 0.72; p < 0.001). Mean strain index value for papillary cell carcinomas (4.09 +/- 0.45) was slightly higher than that for clear cell carcinomas (3.85 +/- 0.78): however, the difference was not statistically significant (p = 0.51). Strain elastography can be used as a valuable imaging technique for preoperative differentiation between RCC and TCC of kidney.
