The management of urethral obstructions is well documented in male cats but is less established for females. These cases describe two female cats that presented with non-dissolvable urocystoliths. Urocystoliths were removed by laser lithotripsy and basket retrieval. Following urolith removal, urethral obstruction occurred in both cats. Both cats were successfully managed using temporary urethral stents in lieu of indwelling urethral catheters permitting outpatient, spontaneous recovery of the urethra.
Use of temporary urethral stents has not been described in cats. These novel stents are constructed from materials available in most veterinary facilities, placed without advanced imaging and reside entirely within the urethra and vestibule. Temporary stents are used to bypass urethral disease, facilitating outpatient recovery, and are easily removed when no longer needed. For these reasons, temporary stents are a cost-efficient alternative to permanent stents or indwelling urinary catheters attached to closed urine-collection systems.
雄性猫尿道梗阻的处理已有详细记录，但雌性猫的相关处理尚不明确。这些病例描述了两只患有不可溶解膀胱结石的雌性猫。通过激光碎石术和网篮取出术取出膀胱结石。在取出尿路结石后，两只猫均发生了尿道梗阻。两只猫均成功使用临时尿道支架替代留置导尿管进行治疗，从而使尿道在门诊情况下自然恢复。
猫使用临时尿道支架的情况此前未见报道。这些新型支架由大多数兽医机构都有的材料制成，无需先进成像技术即可放置，且完全位于尿道和前庭内。临时支架用于绕过尿道疾病，促进门诊恢复，且在不再需要时易于取出。基于这些原因，临时支架是永久性支架或连接到封闭式尿液收集系统的留置导尿管的经济有效替代方案。
