A 6-year-old spayed female 4.4-kg Papillon with only the left kidney presented with vomiting. Imaging unveiled ureterolithiasis and hydronephrosis, while serum chemistry displayed elevated creatinine, blood urea nitrogen, and C-reactive protein. Urinalysis revealed bacteria and bacterial phagocytes. After subcutaneous ureteral bypass (SUB) placement, kidney panels were normalized. The nephrostomy and cystostomy catheters had migrated into the renal parenchyma and bladder wall on postoperative day (POD) 212 and 369, respectively. As the migration advanced, they entered the ureter and bladder on POD 369 and 796, respectively. The SUB, excluding the nephrostomy catheter, was removed on POD 930 due to migration, obstruction, and extrusion of the SUB shunting port. On POD 937, creatinine and BUN levels remained normal. By POD 1063, the ureteroliths had disappeared. This case highlights the need for vigilant monitoring of catheter migration as a potential complication following SUB placement. Early identification and timely intervention are essential for reducing morbidity and improving patient outcomes.
一只6岁、已绝育的4.4千克雌性蝴蝶犬，仅有左肾，出现呕吐症状。影像学检查发现输尿管结石和肾积水，而血清生化检查显示肌酐、血尿素氮和C反应蛋白升高。尿液分析发现细菌和细菌吞噬细胞。在进行皮下输尿管搭桥术（SUB）后，肾功能指标恢复正常。肾造瘘管和膀胱造瘘管分别在术后第212天和369天移入肾实质和膀胱壁。随着移位进展，它们分别在术后第369天和796天进入输尿管和膀胱。由于SUB分流端口的移位、阻塞和挤压，除肾造瘘管外，SUB在术后第930天被取出。术后第937天，肌酐和尿素氮水平仍保持正常。到术后第1063天，输尿管结石消失。该病例强调了在SUB置入后，需密切监测导管移位这一潜在并发症。早期识别和及时干预对于降低发病率和改善患者预后至关重要。
