Abstract:Objective To explore the application value of renal dynamic imaging in diagnosis and
treatment of renal space-occupying lesions. Methods A total of 169 patients with renal space-occupying
preoperative underwent 99mTc-DTPA renal dynamic imaging, to observe and summarize the blood supply
of renal space-occupying lesions in renal dynamic imaging. The relationship between renal function
and Glomerular Filtration Rate (GFR) was observed in 96 patients with malignant tumors who were
postoperative followed up successfully. Results In the 169 cases of kidney placeholder, there are 148
cases with malignant tumor and 21 cases with benign lesion. Of 148 patients with malignant tumor, 117
cases of blood flow on the phase performance is positive; 84.7% of clear cell carcinoma and 20% of
papillary renal cell carcinoma had early blood supply; 2 and 3 scores is the common grades in malignant
tumor group, and benign tumor group is given priority to with 0 and 1, the difference of blood perfusion
score was statistically significant (χ2=27.957,P<0.01). The lesions in diameter of 3~10 cm were
significantly higher than the lesions in diameter less than 3 cm or more than 10 cm in early blood supply
(χ2=19.182,P<0.01). When the contralateral kidney GFR was ≥30 mL/min before surgery, renal function
could maintain the normal level after surgery. And when the contralateral kidney GFR was <30 mL/min,
abnormal renal function mostly appeared. Conclusion Although renal dynamic imaging has less value in
qualitative diagnosing compared with type-B ultrasonic and Computed Tomography Urography (CTU),
but contribute to disease prognosis evaluation.
