Bladder duplication is a rare congenital lower urinary tract anomaly disease characterized by the presence of two bladders, possibly with duplication of the urethra. This disease is rarely reported in cats. The clinical symptoms are commonly occult, with increased difficulty in making a definitive diagnosis, especially if there is no obvious urethral duplication. The diagnosis is typically based on radiographs and ultrasound, with computer tomography serving as a more advanced imaging diagnostic modality. Cases of duplicated bladders with accessory tubular tissues are even scarcer in both human and veterinary medicine.
A 6-year-old male neutered cat was brought to the hospital because of vomiting and constipation. Cystography revealed increased soft tissue density of a fusiform structure in the lower middle abdomen. The purulent-filled cavitary structure and the accessory tubular structure were removed via surgery, and histopathological examination confirmed a double bladder with attached accessory tubular tissue. After antibiotic treatment, the cat recovered uneventfully.
This is the first case of bladder duplication in China and the first case of feline bladder duplication with tubular structure attachment in the world. This information will provide a reference for the diagnosis and treatment of similar cases in the future.
膀胱重复畸形是一种罕见的先天性下尿路畸形疾病，其特征为存在两个膀胱，可能伴有尿道重复。这种疾病在猫中很少见。临床症状通常不明显，确诊难度较大，尤其是没有明显尿道重复时。诊断通常基于 X 光片和超声检查，计算机断层扫描是一种更先进的影像学诊断方式。在人类和兽医医学中，同时存在附件管状组织的重复膀胱病例更为罕见。
一只 6 岁雄性已绝育的猫因呕吐和便秘被带到医院。膀胱造影显示中下腹部出现梭形结构的软组织密度增加。通过手术切除充满脓性液体的囊腔结构和附件管状结构，组织病理学检查证实为具有附件管状组织的双膀胱。经过抗生素治疗，猫恢复良好。
这是中国首例膀胱重复畸形病例，也是世界首例具有管状结构附件的猫膀胱重复畸形病例。这些信息将为未来类似病例的诊断和治疗提供参考。
