To identify the underlying cause of clinical signs in cats with nonobstructive diseases of the bladder and urethra.
Prospective case series.
109 cats examined by the urology service of The Ohio State University's veterinary teaching hospital because of stranguria, hematuria, pollakiuria, or urination in inappropriate locations.
History was obtained and a CBC, serum biochemical analyses, serologic tests for FeLV and feline immunodeficiency virus, urinalysis, bacterial culture of urine, and contrast radiography or urethrocystoscopy (females only) were performed.
16 cats had cystic calculi: 8 had struvite uroliths, 7 had calcium oxalate uroliths, and 1 had a urolith of unknown composition in conjunction with an anatomic defect. Anatomic defects, including diverticulae, urethral strictures, and a malpositioned urethra, were identified in 12 cats. A urinary tract infection was identified in 1 cat, and neoplasia was diagnosed in 2. One of the cats with neoplasia also had a struvite urolith. The remaining 80 cats did not have an anatomic defect, urolith, or tumor. Ten of these cats also did not have radiographic or cystoscopic abnormalities and were presumed to have a behavioral disorder. The remaining 70 cats had radiographic or cystoscopic abnormalities, and idiopathic cystitis was diagnosed. In 14 of the cats with idiopathic cystitis, results of a urinalysis were normal. Cats with idiopathic cystitis were significantly more likely to eat dry food exclusively (59%) than were cats in the general population (19%).
Results suggest that idiopathic cystitis occurs commonly in cats with stranguria, hematuria, pollakiuria, or inappropriate elimination and is associated with consumption of dry foods. Contrast radiography or cystoscopy is necessary for differentiating idiopathic cystitis from behavioral disorders in some cats.
确定患有膀胱和尿道非梗阻性疾病的猫临床症状的潜在病因。
前瞻性病例系列研究。
俄亥俄州立大学兽医教学医院泌尿外科诊治的109只猫，这些猫因排尿困难、血尿、尿频或在不适当位置排尿前来就诊。
获取病史，并进行全血细胞计数、血清生化分析、猫白血病病毒和猫免疫缺陷病毒血清学检测、尿液分析、尿液细菌培养以及造影X线照相术或尿道膀胱镜检查（仅针对雌性猫）。
16只猫有膀胱结石：8只患有鸟粪石尿石，7只患有草酸钙尿石，1只患有成分不明的尿石并伴有解剖学缺陷。在12只猫中发现了解剖学缺陷，包括憩室、尿道狭窄和尿道位置异常。1只猫被诊断为尿路感染，2只被诊断为肿瘤。其中1只患有肿瘤的猫也有鸟粪石尿石。其余80只猫没有解剖学缺陷、尿石或肿瘤。其中10只猫也没有X线照相术或膀胱镜检查异常，推测患有行为障碍。其余70只猫有X线照相术或膀胱镜检查异常，被诊断为特发性膀胱炎。在14只患有特发性膀胱炎的猫中，尿液分析结果正常。患有特发性膀胱炎的猫比一般猫群（19%）更有可能只吃干粮（59%）。
结果表明，特发性膀胱炎常见于排尿困难、血尿、尿频或排尿异常的猫，且与食用干粮有关。在某些猫中，造影X线照相术或膀胱镜检查对于区分特发性膀胱炎和行为障碍是必要的。
