The aim of this study was to investigate causes for feline urethral obstruction and determine whether the frequency of radiographic diagnoses differs between cats radiographed before or after unobstruction of the urethra.
A retrospective cross-sectional study of cats with naturally occurring urethral obstruction was performed. Only cats presenting for their first urethral obstruction in which radiography was integrated in the initial evaluation were included. The diagnosis frequency (overall and for each disease type) was compared between cats radiographed before or after unobstruction of the urethra.
Eighty cats (52%) had radiographs obtained before unobstructing the urethra and 73 cats (48%) had radiographs taken after unobstructing the urethra. Cats radiographed before unobstruction had a greater frequency of radiographic diagnoses than those radiographed after unobstruction (61% versus 45%). This difference was largely due to a greater frequency of urethral plugs detected before unobstruction versus after unobstruction (45% versus 5.5%).
Radiographs obtained before unobstructing the urethra provided a diagnostic advantage for detecting a cause for urethral obstruction compared to radiographs obtained after unobstructing the urethra. Urethral plugs were the most common diagnosis.
本研究旨在探讨猫尿道梗阻的病因，并确定在尿道未梗阻之前或之后进行放射诊断的频率是否存在差异。
对患有自发性尿道梗阻的猫进行了回顾性横断面研究。仅纳入首次出现尿道梗阻且在初始评估中包含放射检查的猫。比较了尿道未梗阻之前和之后进行放射检查的猫的诊断频率（总体和每种疾病类型）。
80 只猫（52%）在未疏通尿道之前进行了放射检查，73 只猫（48%）在疏通尿道之后进行了放射检查。在未疏通尿道之前进行放射检查的猫的放射诊断频率高于疏通尿道之后的猫（61%比 45%）。这种差异主要是由于在未疏通尿道之前检测到的尿道栓的频率高于疏通尿道之后（45%比 5.5%）。
与疏通尿道后进行放射检查相比，在疏通尿道之前进行放射检查可以提供诊断尿道梗阻病因的优势。尿道栓是最常见的诊断。
