血精是泌尿外科及男科的一种常见症状,患者多为小于40岁的中青年男性,多数具有自限性。顽固性血精是指少数血精患者的血精症状经常规药物治疗后仍持续或反复出现,给患者造成巨大的心理压力。磁共振成像(magnetic resonance image,MRI)和经直肠超声检查(transrectal ultrasonography,TRUS)均可为顽固性血精的病因学诊断提供帮助[1,2]。 Blood sperm is a common symptom of urology and men’s surgery. Most of the patients are young and middle-aged men under 40 years old, and most of them are self-limiting. Stubborn semen refers to a small number of patients with blood sperm blood in patients with conventional drug therapy continued or repeated after treatment, causing tremendous psychological pressure on patients. Magnetic resonance imaging (MRI) and transrectal ultrasonography (TRUS) may be helpful in the etiological diagnosis of intractable semen [1,2].
