Urocystolithiasis is a common problem in dogs; many canine uroliths are resistant to medical dissolution. Novel management options would expand, and in some cases improve, current urolith retrieval strategies.
HYPOTHESIS/OBJECTIVES: To describe a previously unreported technique by the Ellik bladder evacuator (EE) to assist in minimally invasive, cystoscopic retrieval of canine cystoliths.
Twelve client-owned dogs presented with urocystolithiasis.
In this retrospective study, dog demographics, procedure type and duration, and clinical outcomes of dogs undergoing cystoscopic cystolith retrieval utilizing the EE are described.
Twelve dogs underwent 13 cystoscopic procedures utilizing EE for cystolith retrieval. The EE was used in accordance with previously described techniques via a custom-made adaptor. Ten dogs were spayed females; 8 different breeds were represented. In 8 of 13 procedures, transurethral cystoscopy alone by EE with or without wire basket or grasping forceps was performed with a median procedure duration of 36 minutes (range, 16-52). In the other 5 procedures, additional interventions (ie, laser lithotripsy, percutaneous perineal approach, urethral stricture ballooning, ethanol parathyroid ablation) were performed as indicated with a median procedure duration 110 minutes (range, 42-144). No complications were noted in association with the use of the EE; retrieval of cystoliths was complete in 12 of 13 procedures.
Use of the EE during cystoscopy might aid in minimally-invasive retrieval of cystoliths. This work provides a starting point for additional discussion regarding its benefit relative to current interventions.
膀胱结石在犬类中是一个常见问题；许多犬类尿路结石对药物溶解有抗性。新的治疗选择将扩展并在某些情况下改善当前的尿路结石取出策略。
假设/目标：描述一种此前未报道的使用埃利克膀胱排空器（EE）辅助进行犬膀胱结石微创膀胱镜取出的技术。
12只客户拥有的患有膀胱结石的犬。
在这项回顾性研究中，描述了犬的人口统计学特征、手术类型和持续时间，以及使用EE进行膀胱镜下膀胱结石取出的犬的临床结果。
12只犬接受了13次使用EE进行膀胱结石取出的膀胱镜手术。EE通过定制适配器按照先前描述的技术使用。10只犬为绝育雌性；代表了8个不同品种。在13次手术中的8次，仅通过EE经尿道膀胱镜检查，使用或不使用金属丝篮或抓钳，中位手术持续时间为36分钟（范围16 - 52分钟）。在其他5次手术中，根据需要进行了额外干预（即激光碎石术、经皮会阴途径、尿道狭窄球囊扩张、乙醇甲状旁腺消融），中位手术持续时间为110分钟（范围42 - 144分钟）。未发现与使用EE相关的并发症；13次手术中有12次结石取出完全。
膀胱镜检查期间使用EE可能有助于膀胱结石的微创取出。这项工作为进一步讨论其相对于当前干预措施的益处提供了一个起点。
