Plain-English summary
A 5-year-old male miniature dachshund was diagnosed with bladder and prostate cancer and later developed a blockage in his ureters. To relieve this blockage, veterinarians placed stents in his ureters, but two weeks later, the dog developed lumps at the sites where the stents were inserted. Surgery was performed to remove these lumps, which were found to be cancerous tissue that likely spread during the stenting procedure. While ureteral stenting can help with urinary blockages caused by tumors, pet owners should be aware of the risk of spreading cancer during the process.

Abstract
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.
