A 10-year-old Irish Sport Horse gelding developed complications from a general anesthesia resulting in sling support and recurrent urinary catheterization. The horse subsequently presented signs of dysuria and pollakiuria, was diagnosed with sabulous cystitis, and developed a urethral stricture from the repeated catheterizations, which was confirmed on urethroscopy. Clinical signs persisted despite conservative management with topical corticosteroids and urethral bougienage with balloon dilators. An image-guided approach was used to treat the stricture with a custom-made polydioxanone stent placed in the urethra after which the horse was able to void normally and fully empty his bladder. Repeat urethroscopy and ultrasonography 6 months after the procedure showed the stent to have completely reabsorbed with urethra remaining patent. Nineten months after the procedure, the owner reports the horse remaining at his intended level of athletic performance with no dysuria.
一匹 10 岁的爱尔兰运动马骟马在全身麻醉后出现并发症，需要吊带支撑并反复进行导尿。随后，这匹马出现排尿困难和尿频的症状，被诊断为砂囊膀胱炎，并因反复导尿而出现尿道狭窄，这在尿道镜检查中得到了证实。尽管采用局部皮质类固醇和球囊扩张器进行尿道扩张等保守治疗，但临床症状仍持续存在。采用图像引导的方法，用定制的聚二氧杂环己酮支架治疗狭窄，然后马能够正常排尿并完全排空膀胱。术后 6 个月进行重复尿道镜检查和超声检查显示，支架完全吸收，尿道保持通畅。术后 19 个月，主人报告说这匹马仍保持着预期的运动表现水平，没有排尿困难。
