End-to-end ureteral anastomosis and double-pigtail ureteral stent placement for treatment of iatrogenic ureteral trauma in two dogs

Abstract

The surgical technique used provided a viable option for preserving renal function in dogs with focal, iatrogenic ureteral trauma. Use of a ureteral stent facilitated ureteral anastomosis and minimized postoperative complications.

Treatment and outcomes of ureter injuries due to ovariohysterectomy complications in cats and dogs

“…Case reports have described the presentation and treatment of one or two female cats or dogs suffering from ureter ligation and/or transection (Nwadike et al 2000, Mehl & Kyles 2003, Kang et al 2007, Ávila Filho et al 2014, Johnson et al 2015, Wormser et al 2015, concurrent ureter and bladder ligation (Ewers & Holt 1992), ureter resection (Kyles et al 1996) and ureter occlusion secondary to adhesions or granuloma formation at the ovarian or cervical stumps (Ruiz de Gopegui et al 1999, Kanazono et al 2009, Cerqueira da Silva 2016) following ovariohysterectomy. The repair methods used in these case reports were variable, including end-to-end ureter anastomosis with or without stent placement (Mehl & Kyles 2003, Kanazono et al 2009, Wormser et al 2015, ureteronephrectomy (Kyles et al 1996, Kang et al 2007, Ávila Filho et al 2014, Cerqueira da Silva 2016), ureteroneocystostomy (Nwadike et al 2000) and subcutaneous ureteral bypass (SUB) placement (Johnson et al 2015). One dog with bilateral ureter injuries, end-stage renal failure and concurrent adrenal neoplasia was euthanased (Ruiz de Gopegui et al 1999), and a cat with bilateral ureter transection was successfully treated with bilateral neoureterostomy (Nwadike et al 2000).…”

“…One dog with bilateral ureter injuries, end-stage renal failure and concurrent adrenal neoplasia was euthanased (Ruiz de Gopegui et al 1999), and a cat with bilateral ureter transection was successfully treated with bilateral neoureterostomy (Nwadike et al 2000). The other reports involved animals with unilateral ureter injuries, all of which survived corrective surgeries with only minor complications (Kyles et al 1996, Mehl & Kyles 2003, Kang et al 2007, Kanazono et al 2009, Ávila Filho et al 2014, Johnson et al 2015, Wormser et al 2015, Cerqueira da Silva 2016.
