目的探讨附睾部位梗阻性无精子症发病危险因素及临床特征。方法回顾性分析2014年1月至2015年12月期间收治的141例附睾梗阻性无精子症患者资料,分为单纯性附睾梗阻组89例与复杂性附睾梗阻组52例,分析比较两组患者年龄、病史、精液量、精液p H值以及常见危险因素。所有患者均经手术确诊。结果复杂性附睾梗阻组中有泌尿生殖系感染病史者(13例),有腹股沟疝修补术史者(10例),明显多于单纯性附睾梗阻组(P≤0.001),单纯性附睾梗阻组中有长期吸烟史者30例,明显多于复杂性附睾梗阻组(P=0.036)。结论泌尿生殖系感染与腹股沟疝修补术可能是复杂性附睾梗阻性无精子症的危险因素,吸烟可能是单纯性附睾梗阻性无精子症重要影响因素之一,大部分附睾梗阻性无精子症患者的病因不清。
Objective To explore the risk factors and clinical features of obstructive azoospermia at epididymal site. Methods The data of 141 cases of epididymal obstructive azoospermia admitted from January 2014 to December 2015 were retrospectively analyzed. There were 89 cases with simple epididymal block and 52 cases with complex epididymal obstruction. The clinical data of two groups were compared Age, medical history, sperm volume, semen p H value, and common risk factors. All patients were confirmed by surgery. Results Complication of epididymal obstruction group had a history of genitourinary infection (13 cases), history of inguinal hernia repair (10 cases), significantly more than simple epidural block group (P≤0.001), simple epidural block group There were 30 patients with long-term smoking history, which was significantly more than that of complicated epidural block (P = 0.036). Conclusions Genitourinary infection and inguinal hernia repair may be the risk factors of complicated epididymal obstructive azoospermia. Smoking may be one of the most important influencing factors of simple epididymal obstructive azoospermia. Most patients with epididymal obstructive azoospermia The cause is unclear.
