We aimed to evaluate and compare the clinical diagnostic values of magnetic resonance imaging (MRI) and ultrasound in patients with intractable haematospermia. We performed a retrospective review of 23 patients with intractable haematospermia who were diagnosed with seminal vesicle haematocele and/or calculi by transurethral seminal vesiculoscopy (TSV). Patients' demographics, disease durations, operative times, and MRI and transrectal ultrasound (TRUS) results were recorded. McNemar's test was used to compare the positive diagnostic rates of MRI and TRUS. All patients had undergone preoperative seminal vesicle MRI and TRUS to identify the aetiology of the haematospermia. The average age and disease duration were 39.3 years and 24.1 months, respectively. The mean operative time was 81.1 min. The positive result rates for MRI and TRUS were 95.7% (22/23) and 39.1% (9/23), respectively. Compared with TRUS, MRI had a significantly higher preoperative positive diagnostic rate (p < 0.01). These results suggest that MRI should be considered as a method for diagnosing intractable haematospermia in patients when TRUS findings are negative or inconclusive.
我们旨在评估和比较磁共振成像（MRI）和超声在顽固性血精症患者中的临床诊断价值。我们回顾性分析了 23 例经尿道精囊镜检查（TSV）诊断为精囊血肿和/或结石的顽固性血精症患者。记录了患者的人口统计学资料、疾病持续时间、手术时间以及 MRI 和经直肠超声（TRUS）结果。采用 McNemar 检验比较 MRI 和 TRUS 的阳性诊断率。所有患者均接受了术前精囊 MRI 和 TRUS 检查，以确定血精的病因。平均年龄和疾病持续时间分别为 39.3 岁和 24.1 个月。平均手术时间为 81.1 分钟。MRI 和 TRUS 的阳性结果率分别为 95.7%（22/23）和 39.1%（9/23）。与 TRUS 相比，MRI 术前阳性诊断率显著更高（p<0.01）。这些结果表明，当 TRUS 检查结果为阴性或不确定时，MRI 应被视为诊断顽固性血精症的一种方法。
