Reconstruction Of The Ureter With An Autogenous External Jugular Vein Graft In A Bitch Model [electronic resource].

Includes references.

Seven apparently healthy mongrel bitches were used in the present study to assess the suitability of the autogenous external jugular graft for ureteral reconstruction. A 2-cm left ureteral segment was resected and replaced with a 2-cm segment of external jugular vein graft by end-to-end anastomosis in a simple interrupted suture pattern using 6-0 prolene. Results showed that all bitches appeared clinically normal throughout the period of the study. Twelve weeks postoperatively, the left ureter appeared unstained at the X-Ray film using urographine as a contrast media in all cases. Abdominal ultrasonography showed enlargement of the left kidney and dilation of the anechoic renal pelvis at 6 &12 weeks postoperatively. Macroscopically, there was an intense fibrous reaction at the site of the graft with adhesions to the surrounding structures. Microscopically, the submucosa of the graft showed transformation into cartilage (cartilaginous metaplasia). The kidney had multiple cystic dilatations of the renal tubules. In conclusion, the autogenous external jugular graft seems to be unsuitable for ureteral reconstruction in bitches.
