Abstract:

Objective　To evaluate the diagnostic value of ultrasonography guided fine needle aspiration for testis tissue.  Methods  The tissue slices of the testis through fine needle aspiration and core needle biopsy were collected from January 2015 to December 2016, the difference in the number of microtubules was compared. In addition, the differences in other ingredients (skin, blood vessels and fibrosoft tissue) and hematoma were analyzed.　Results　The testicle histopathological sections collected by core needle puncture or fine needle aspiration presented more than 20 seminiferous tubule sections for 8 patients in the core needle group and 11 patients in the fine needle group , without statistically significant difference between the two groups （χ2=2.087，P=0.149）; additional components were present in the sections for 19 patients in the core needle group and 1 patient in the fine needle group, with statistically significant difference between the two groups(χ2 =24.203，P=0.000); 5 patients in the core needle group and 0 patient in the fine needle group experienced post-puncture hematoma, with statistically significant difference between the two groups（χ2=4.70，P=0.032）.　Conclusion　The fine needle aspiration of testicular tissue is satisfactory, and almost no other components interfere with it, and have great clinical application value.
