Urinary tract infections (UTIs) are common in female dogs and recurrent infections often require investigation by transurethral cystoscopy.
HYPOTHESIS/OBJECTIVES: Describe the findings of transurethral cystoscopy in dogs presented for recurrent urinary tract infections (RUTI).
Fifty-three client-owned dogs with RUTI were included in the study.
Retrospective study. Data collected from medical records included signalment, clinical findings, bladder wall culture, cystoscopic, and histopathologic findings. UTI was defined as: presence of compatible clinical signs and at least 2 out of 3 of the following criteria: (1) pyuria, (2) positive urine culture, (3) resolution of clinical signs with antibiotic treatment. Recurrence of UTI was defined as at least 2 episodes of UTI within 6 months or at least 3 or more in 1 year.
The mean age at presentation was 3.8 years with a majority of female dogs (48/53), 40/48 of which were spayed. Main breeds were Labrador (10/53), Australian Shepherd (4/53), and Miniature Schnauzer (3/53). A hooded vulva was noted in 33/48 of females. Transurethral cystoscopy showed anomalies in 45/53 of cases: mucosal edema (19/53), vestibulovaginal septal remnant (15/48), lymphoid follicles (8/53), short urethra (6/53), and ectopic ureter (5/53). Urine culture at the time of cystoscopy was positive in 13/49. Bladder wall edema and ulceration were the most common findings on histopathology (25/39).
RUTI occurred more frequently in spayed female dogs. Transurethral cystoscopy is useful in the diagnosis and treatment of anomalies in dogs with RUTIs.
尿路感染（UTI）在雌性犬中很常见，复发性感染通常需要经尿道膀胱镜检查进行调查。
假设/目的：描述因复发性尿路感染（RUTI）就诊的犬经尿道膀胱镜检查的结果。
本研究纳入了 53 只患有 RUTI 的患犬。
回顾性研究。从病历中收集的数据包括年龄、临床发现、膀胱壁培养、膀胱镜和组织病理学发现。UTI 的定义为：存在相符的临床症状，且至少符合以下 3 项标准中的 2 项：（1）脓尿，（2）尿液培养阳性，（3）用抗生素治疗后临床症状缓解。UTI 的复发定义为在 6 个月内至少发生 2 次 UTI，或在 1 年内发生 3 次或更多次 UTI。
就诊时的平均年龄为 3.8 岁，大多数为雌性犬（48/53），其中 40/48 只犬已绝育。主要品种为拉布拉多犬（10/53）、澳大利亚牧羊犬（4/53）和迷你雪纳瑞犬（3/53）。在 48 只雌性犬中有 33 只存在阴唇遮盖。经尿道膀胱镜检查显示 45/53 例存在异常：黏膜水肿（19/53）、前庭阴道隔残迹（15/48）、淋巴滤泡（8/53）、尿道短（6/53）和异位输尿管（5/53）。在 49 次膀胱镜检查时，有 13 次尿液培养阳性。膀胱壁水肿和溃疡是组织病理学最常见的发现（25/39）。
绝育雌性犬 RUTI 更常见。经尿道膀胱镜检查对诊断和治疗 RUTI 犬的异常很有用。
