彩色多普勒超声在无精子症患者睾丸穿刺活检中的应用价值

Application value of color doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy

目的探讨彩色多普勒超声在无精子症患者睾丸穿刺活检中的应用价值。方法回顾性分析2012年11月—2015年2月在我科诊断为无精子症的53例患者的病例资料。所有患者进行常规阴囊超声检查,采用频谱多普勒检测睾丸动脉(TA)、睾丸内动脉(ITA)的收缩期最大速度(PSV)、舒张末期速度(EDV)和阻力指数(RI)。采用彩色多普勒超声观察睾丸内的血管分布及其数目,并进行半定量评分。所有患者进行睾丸穿刺活检并进行Johnsen评分。结果 47例患者诊断为梗阻性无精子症(OA),6例患者诊断为非梗阻性无精子症(NOA)。0A组睾丸的平均体积(15.3±3.6)m L,NOA组睾丸的平均体积(7.1±2.8)m L,差异有统计学意义(P<0.01);OA组与NOA组患者睾丸的血流参数(PSV、EDV、RI)结果有统计学意义(P<0.05);OA组与NOA组睾丸内血管半定量分级有的差异,其差异有统计学意义(P<0.01)。结论彩色多普勒超声检查对睾丸生精功能有很好的预测作用,可作为鉴别OA患者和NOA患者的指标。

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 eases patients with azoospermia from 2012 November to 2015 February in our department. All patients underwent routine scrotal uhrasonography, to detecte the peak systolic velocity （ PSV）, end diastolic velocity （EDV） and resistance index （RI） of testicular artery （TA） and intratesticular artery （ITA） with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia（ OA）, 6 patients were diagnosed as non obstructive azoospermia（NOA）. The average volume of testis was （ 15.3 ±3.6） mL in OA group. The average volume of testis was （7. 1 ± 2. 8 ） mL in NOA group. There was significant difference （ P 〈 0. 01 ）. The blood flow parameters （ PSV, EDV, RI） results between OA group and NOA group have obvious difference, the difference was statistically significant （ P 〈 0.05）. The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference, the difference was statistically significant （P 〈 0. 01 ）. Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.
