A 5 yr old castrated male miniature dachshund presented with clinical signs attributable to carcinoma involving the bladder neck and prostate. On day 84 following diagnosis, the dog developed bilateral ureteral obstruction and ureteral stenting was attempted. The stents were inserted in a normograde fashion via percutaneous puncture of the dilated renal pelvises. Two wk later, the dog developed nodules at both sites of renocentesis. En block resection of the masses was performed, and histologic examination confirmed that the masses were urothelial carcinoma, likely caused by iatrogenic tumor seeding. Ureteral stenting is a useful technique to relieve malignant ureteral obstruction; however, risk of iatrogenic tumor seeding must be considered.
一只5岁去势雄性迷你腊肠犬出现了归因于膀胱颈和前列腺癌的临床症状。诊断后第84天，该犬出现双侧输尿管梗阻，并尝试进行输尿管支架置入术。通过经皮穿刺扩张的肾盂以顺行方式插入支架。两周后，该犬在肾穿刺的两个部位出现结节。对肿块进行了整块切除，组织学检查证实肿块为尿路上皮癌，可能是由医源性肿瘤种植引起的。输尿管支架置入术是缓解恶性输尿管梗阻的一种有用技术；然而，必须考虑医源性肿瘤种植的风险。
