Comparison of 3 Techniques for Ureteroneocystostomy in Cats

Abstract

An extravesical ureteroneocystostomy technique using a simple interrupted pattern for anastomosis should be considered in cats undergoing renal transplantation.

Endoscopic placement of ureteral stents for treatment of congenital bilateral ureteral stenosis in a dog

“…For veterinary patients with ureteral stenosis, the traditional options typically include ureteral resection and anastamosis, ureteroureterostomy, ureteronephrectomy, or ureteroneocystostomy. 4,39 Postoperative ureteral strictures and ureteral leakage are the most concerning potential surgical risks, 40 and the difficulties of reimplantation and manipulation of the ureters in this particular proximal location were strongly considered. Obviously, ureteronephrectomy was not an option because of the bilateral nature of the disease in the dog of this report; even if the disease had been unilateral, this procedure would not be recommended.…”

A Comparison of Continuous and Interrupted Suturing in Laparoscopic Pyeloplasty

“…6–8,10,11 Most of the experimental studies were done in laboratory animals and mainly involved bowel anastomoses. Sarin et al concluded that there was no significant increase in the incidence of leak or tissue damage with continuous sutures, although previous reports suggest that there can be vascular compromise with continuous suturing.…”

“…3,4 Although continuous sutures are more watertight compared with interrupted sutures, 5 the possibility of seeing the purse-string effect and tissue damage may be a concern. 6–8 We present the results of our retrospective analysis of the effects and outcome of continuous and interrupted sutures during laparoscopic pyeloplasty.…”

Urinary Obstruction: Ureteral Obstruction

“…Leakage of urine from the ureterotomy or anastomosis site has been reported in 2-18% of cases [9,17,18]. The risk of this complication is reduced with the experience of the surgeon.…”

“…17 The ureteral wall is sutured to the mucosal layer of the bladder, starting at the crotch of the spatulated ureter.…”
