A retrospective analysis was made of 30 cases of canine prostatic disease, with the objective of identifying (via a prepubic approach) the 2-dimensional, gray-scale ultrasonographic appearance most often associated with the various spontaneous prostatic diseases. Ultrasonography was of value in characterizing the parenchymal architecture as normal vs focally hyperechoic and diffusely hyperechoic (associated with chronic inflammation and neoplasia) or focally hypoechoic or anechoic (either accompanied by distant enhancement), which was associated with retention cyst or abscess. Further specificity based only on abnormal echotexture was not possible. Ultrasonography facilitated the differentiation of radiographically identifiable prostatomegaly attributable to abscess or neoplasia from apparent prostatomegaly attributable to paraprostatic cyst. An imaging protocol consisting of distention retrograde urethrocystography and prepubic ultrasonography was recommended, as a distended bladder aided ultrasonographic identification of the prostate gland. In addition, the combination of urethral morphologic features and urethroprostatic reflux appearance complemented the ultrasonographic appearance for differentiation of prostatic abscess from prostatic carcinoma. A classification scheme for spontaneous canine prostatic disease combining germane imaging morphologic features with microscopic and microbiologic findings was proposed.
对30例犬前列腺疾病进行回顾性分析，目的是（通过耻骨前途径）确定与各种自发性前列腺疾病最常相关的二维灰阶超声表现。超声检查对于将实质结构特征化为正常、局灶性高回声和弥漫性高回声（与慢性炎症和肿瘤形成相关）或局灶性低回声或无回声（伴有后方增强）具有价值，后者与潴留囊肿或脓肿相关。仅基于异常回声纹理无法获得进一步的特异性。超声检查有助于区分因脓肿或肿瘤形成导致的影像学上可识别的前列腺肿大与因前列腺旁囊肿导致的明显前列腺肿大。推荐采用逆行尿道膀胱造影和耻骨前超声检查组成的成像方案，因为充盈的膀胱有助于超声识别前列腺。此外，尿道形态特征和尿道前列腺反流表现的结合补充了超声表现，用于区分前列腺脓肿和前列腺癌。提出了一种将相关成像形态特征与微观和微生物学发现相结合的自发性犬前列腺疾病分类方案。
