作者对276例男性不育的病人作了经直肠US(TRUS)研究。年龄24～52岁,均为射精量少(<1.5ml)及无精子。病人左侧卧位,用7.5～9.0MHz高频直肠内换能器,行横断面和矢状面检查输精管末端、精囊、射精管和前列腺,并记录测定结果,仔细注意内部回声及输精管和精囊的结构。所有病人均作了肾US以发现潜在的肾异常。 结果显示,除70例(25.4％)TRUS未发现解剖学异常外,其余病人均有异常,包括先天性双侧输精管缺如或发育不良94例(34.1％),双僻输精管闭
The authors undertook a transrectal US (TRUS) study of 276 male infertile patients. Aged 24 to 52 years old, both less ejaculation (<1.5ml) and no sperm. Patients in the left lateral position, with 7.5 ~ 9.0MHz high-frequency rectal transducer, cross-section and sagittal examination of the vas deferens, seminal vesicle, ejaculatory duct and prostate, and record the results of the measurement, careful attention to the internal echo and vas deferens and seminal vesicle Structure. All patients underwent kidney US to detect potential renal abnormalities. The results showed that, except 70 cases (25.4%) TRUS did not find anatomic abnormalities, the other patients were abnormal, including congenital bilateral absence or dysplasia of ducts in 94 cases (34.1%), double seclusion of vas deferens
