To analyze the medical images and therapeutic strategies in patients with prostatic abscesses.
From April 1999 to August 2002, 12 patients with prostatic abscesses at Srinagarind Hospital, Khon Kaen, Thailand were reviewed The average age was 47 years (range 29 to 75). Diagnostic procedures included analysis of midstream urine, abscess fluid for pathogens and medical imaging with TRUS, CT and MRI. Therapeutic options were transrectal ultrasound-guided drainage or conservative medical treatment.
Almost all patients had predisposing diseases. All patients showed hypo-echoic masses, plus internal septation in 5 cases. Most lesions were located at the central gland. Their sizes ranged from 0.5 to 2.75 cm (average 1.51 cm) in diameter. The main pathogen was B. pseudomallei. On TRUS imaging, patients with melioidosis had one or more hypo-echoic areas with internal septation, thickened wall and surrounding multiple small daughter abscesses. All abscesses resolved within 4 weeks, with no difference in the duration of treatment, despite different sizes or pathogens.
Transrectal ultrasonography is useful in the diagnosis of prostatic abscess as well as in the guidance for aspiration and the drainage of such abscesses. Our data showed sonographic patterns in prostatic abscess, especially with melioidosis.
分析前列腺脓肿患者的医学影像及治疗策略。
回顾1999年4月至2002年8月泰国孔敬诗里拉医院收治的12例前列腺脓肿患者。平均年龄47岁（范围29至75岁）。诊断程序包括分析中段尿、脓肿液中的病原体以及经直肠超声（TRUS）、CT和MRI等医学成像检查。治疗选择为经直肠超声引导下引流或保守药物治疗。
几乎所有患者都有易感疾病。所有患者均显示低回声肿块，其中5例伴有内部间隔。大多数病变位于中央腺体。其直径范围为0.5至2.75厘米（平均1.51厘米）。主要病原体为类鼻疽杆菌。在TRUS成像中，类鼻疽病患者有一个或多个伴有内部间隔、壁增厚及周围多个小子脓肿的低回声区。所有脓肿在4周内均消退，无论大小或病原体如何，治疗持续时间均无差异。
经直肠超声检查对前列腺脓肿的诊断以及抽吸和引流的引导均有用。我们的数据显示了前列腺脓肿的超声图像特征，尤其是类鼻疽病相关的特征。
