There are limited studies on cystoscopic-guided laser ablation for treating ectopic ureters in male dogs. Further investigation is needed to assess its safety and efficacy.
HYPOTHESIS/OBJECTIVE: Retrospectively describe long-term outcomes in male dogs treated using cystoscopic-guided laser ablation of ectopic ureters (CLA-EU).
Eighteen client-owned male dogs.
Medical records of male dogs that had CLA-EU performed were retrospectively reviewed. Continence scores were assigned before and after the procedure. Data collected included signalment, neuter status, age of onset of urinary incontinence, pre- and post-operative continence scores, CBC, serum biochemistry, urinalysis, microbiological urine culture, pre- and post-operative abdominal imaging, EU laterality, concurrent anatomic anomalies, laser type and size used, procedure time, complications, and follow-up.
The procedure was performed successfully in all 28 ureters in the 18 dogs. Post-operative continence scores were significantly improved from pre-operative scores (p = 0.001). Four (22%) dogs were continent at the time of diagnosis. Of the 14 dogs initially incontinent, 11/14 (79%) became continent after CLA-EU without additional treatments, and an additional dog became continent with the addition of medications. Preoperatively, 14/28 kidneys and 17/28 ureters had evidence of hydronephrosis and hydroureter, respectively. Of the dogs, 10/14 with hydronephrosis and 12/17 with hydroureter showed improvement on post-operative ultrasonography. The median follow-up time was 1789 days (range, 98-3560).
In male dogs, CLA-EU was a safe, effective, and minimally invasive procedure with good to excellent short- and long-term outcomes, achieving continence in most dogs and improvement or stabilization of associated hydronephrosis and hydroureter.
关于膀胱镜引导下激光消融治疗雄性犬异位输尿管的研究有限。需要进一步研究以评估其安全性和有效性。
假设/目的：回顾性描述采用膀胱镜引导下激光消融异位输尿管（CLA-EU）治疗的雄性犬的长期预后。
18只客户拥有的雄性犬。
对接受CLA-EU治疗的雄性犬的病历进行回顾性分析。在手术前后进行控尿评分。收集的数据包括特征、去势状态、尿失禁发病年龄、术前和术后控尿评分、血常规、血清生化、尿液分析、微生物尿培养、术前和术后腹部影像学检查、异位输尿管的侧别、并发解剖异常、使用的激光类型和尺寸、手术时间、并发症及随访情况。
18只犬的28条输尿管均成功完成手术。术后控尿评分较术前显著改善（p = 0.001）。4只（22%）犬在诊断时即已控尿。在最初尿失禁的14只犬中，11/14（79%）在CLA-EU术后无需额外治疗即实现控尿，另有1只犬在添加药物后实现控尿。术前，28只肾脏中的14只和28条输尿管中的17条分别有肾积水和输尿管积水的证据。在这些犬中，10/14有肾积水和12/17有输尿管积水的犬在术后超声检查中显示病情改善。中位随访时间为1789天（范围98 - 3560天）。
在雄性犬中，CLA-EU是一种安全、有效且微创的手术，短期和长期预后良好至极佳，多数犬实现控尿，相关肾积水和输尿管积水得到改善或稳定。
