title: Unilateral hydronephrosis and partial ureteral obstruction by entrapment in a granuloma in a spayed dog.
abstract: A 6-year-old, spayed female dog had hydronephrosis and incomplete ureteral occlusion on the left side. An end-to-side ureteral anastomosis was performed. The incomplete ureteral occlusion was determined to be related to an ovarian pedicle granuloma formation and was presumably related to a reaction to the suture material used for ovariohysterectomy (OVH) performed 5 years prior to presentation. Azotemia and hydronephrosis were dramatically improved after surgery, and renal function has been well maintained for 3 years. To the authors' knowledge, a chronic partial ureteral occlusion associated with an ovarian pedicle granuloma from an OVH has not been reported.
