Clinical diagnostic value of color Doppler ultrasound in evaluating brucellosis with orchitis / 中华地方病学杂志

ABSTRACT

Objective To evaluate the clinical diagnostic value of color Doppler ultrasound in diagnosis brucellosis with orchitis.Methods Hospital-based case-control study was used.We selected the patients with brucellosis orchitis who were hospitalized in Heilongjiang Land Reclamation Bureau General Hospital from 2014 to 2016 as a case group.At the same time,selected healthy people as the control group.Bilateral testicular size,parenchyma echo,flow signals in parenchyma,depth of bilateral testicular sheath membrane cavity effusion,testicular artery peak systolic velocity (PSV),end-diastolic velocity (EDV),pulsatility index,resistance index,peak systolic velocity/end-diastolic velocity,were measured and analyzed using color Doppler ultrasound.Results The case group included 62 patients;the health control group included 41 persons.The testicular volume of case group was compared to that of healthy control group,there was no statistical significant difference (cm315.81 ± 3.27 vs 15.82 ± 2.77,t =0.015,P ＞ 0.05).By analyzing the correlation between the course of the disease and the testicular volume,a negative relationship was found (r =-0.594,P ＜ 0.01).In the case group,the deep diameter of the testicular sheath was higher than that of the healthy control group,and the difference was statistically significant (cm1.50 ± 0.53 vs 0.84 ± 0.21,t =10.777,P＜ 0.01).The PSV and EDV were higher than those in the control group (cn/s(9.73 ± 3.25 vs 6.00 ± 1.38,2.89 ± 0.77 vs 2.46 ± 0.36,t =9.810,4.691,P ＜ 0.01).The pulsation index and resistance index were higher than that in the control group (1.06 ± 0.12 vs 0.82 ± 0.08,0.69 ± 0.05 vs 0.58 ± 0.04,t =15.678,12.763,P ＜ 0.01).Conclusions There are specific changes in Brucella patients with orchitis.The blood flow spectrum and testicular sheath membrane cavity effusion are specific changes.The color Doppler ultrasound can effectively evaluate Brucella orchitis patients with testicular injury,provide a reliable imaging basis for clinical treatment.
