Abstract: Objective To investigate the 36 cases of urinary tuberculosis on high resolution computed tomography (HRCT) appearances and the value of imaging in guiding therapy, and to improve the diagnostic consistency rate and provide the basis for standard treatment. Methods A retrospective analysis of 36 cases of urinary tuberculosis cases confirmed by pathology and clinical data, to study HRCT scanning technique of urinary tuberculosis, imaging findings of CT plain and enhanced scan and to evaluate HRCT in the role of urinary tuberculosis treatment options.Results (1) Of 36 cases of urinary tuberculosis HRCT scan and enhancement were found in 3 patients with early renal tuberculosis, characterized by small low density lesions in the renal parenchyma. (2) In the renal multiple petal shaped low-density area in 25 cases, renal diffuse calcification that since the cut in 2 cases, renal cortical atrophy thinning in 4 cases, 10 cases of renal atrophy, renal pelvis or light wall thickening in 4 cases; Three cases of retroperitoneal lymph nodes of visible multiple sizes. (3) The HRCT scan and enhancement, infringement on the scope and degree of viscera and the surrounding tissue to evaluate and swollen lymph nodes, according to this decision on operation mode and operation time. Conclusion renal parenchyma in smaller low-density lesions, within multiple petal shaped low-density lesions after enhancement scanning area disc wall showed cricoid moderately delayed reinforcement, and irregular calcification is the imaging characteristics of renal tuberculosis. Based on HRCT imaging performance characteristics can provide objective basis for the choice of clinical treatment.
