概括
计算机断层分泌泌尿学 (CTEU) 在预测犬的尿道解剖学方面显示出有限的准确性,CT发现通常需要囊镜确认. 外科医生在解释CTEU结果时应考虑这些局限性,以规划外宫尿管治疗.
科学领域:
- 兽医辐射学 兽医辐射学
- 狗类泌尿病学 狗类泌尿病学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 宫外尿道是狗中尿失禁的常见原因.
- 计算机断层分泌泌尿图 (CTEU) 越来越多地用于诊断尿管异常.
- 对尿道解剖学的准确的术前评估对于成功的手术干预至关重要.
研究的目的:
- 评估CTEU在预测尿管解剖学方面的诊断准确性,与囊镜检测结果相比.
- 为了确定CTEU的接收器操作特征 (ROC),用于识别正常,室内和室外外宫外尿道.
- 评估CTEU在预测尿道孔位置方面的准确性.
主要方法:
- 对35只客户拥有的狗进行了回顾性队列研究,怀疑有宫外尿道.
- 检查医疗记录,包括CTEU和囊镜检查结果.
- 接收器操作特征 (ROC) 分析,以比较CT预测的尿管解剖学和孔位位置与囊泡镜检测结果.
主要成果:
- CT在50%和78%的病例中正确识别了正常和宫外尿道.
- 对于区分外腔尿道和内腔尿道的灵敏度和特异性有显著的变化 (29%与65%的灵敏度,97%与71%的特异性).
- 在确定子宫外尿管孔位置的CT精度显示出很大的差异 (0%至76%的灵敏度).
结论:
- 在预测狗尿管解剖学方面,CTU并不总是准确.
- 囊管镜检查和潜在的手术内光镜检查是必要的,以确认CTEU发现在手术规划之前,特别是尿管孔位置.
- 在确定尿道关附近的尿道孔时,CTU的低灵敏度可能会影响手术决策.

01:10Computed Tomography
4.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
