Ureter: neoureterostomy

Contributor(s): David Moll, Graham Munroe, Madeleine Campbell

Introduction

  • Vesicoureteral anastomosis is the method of choice in other species for the treatment of ectopic ureters Skin: urine scald 01and ureteral avulsion.
  • In the horse these conditions are rare and neoureterostomy is only occasionally used.

Uses

  • Implantation of ureter into correct position within the bladder, eg ectopic ureter. An ectopic ureter leaves the kidney but does not enter the bladder in the normal position.
  • Ectopic ureters may not be noticed until a foal is several weeks old, when urinary incontinence / urine scalding on the perineum may become evident.

Advantages

  • Method of choice to re-establish correct vesicoureteral anastomosis.
