Plain-English summary
A Miniature Pinscher was brought in with severe lethargy, no urine output, and abdominal pain. Tests showed that the dog had a blockage in the ureters likely caused by xanthine stones, which developed after treatment with allopurinol for leishmaniasis. The veterinarian placed a subcutaneous ureteral bypass to relieve the obstruction, and the dog recovered well, with kidney function improving within days. Over three years of follow-up, the dog had no complications related to the bypass and was switched to a different medication for leishmaniasis without issues.

Abstract
This case report describes the long-term success of a subcutaneous ureteral bypass device in a dog for treatment of a ureteral obstruction. The suspected xanthine urolithiasis was secondary to treatment with allopurinol for leishmaniasis. The dog presented initially with lethargy, anuria and abdominal pain. Mild azotemia was found on biochemical analysis and abdominal ultrasound revealed bilateral ureteral obstruction. A subcutaneous ureteral bypass was subsequently placed using a standard surgical technique. The dog recovered uneventfully and the azotemia resolved within days. Follow-up examinations were performed every trimester for over three years and no complications like obstruction of the bypass tubes, urinary tract infection or azotemia were recognized during this follow-up period. Allopurinol was replaced with domperidone as long-term treatment against Leishmaniasis which resulted in a mild increase of the leishmania serum antibody titer. The subcutaneous ureteral bypass placement was successful and safe in this dog and is a valuable alternative in cases of ureteral obstruction also in dogs.
