Ureter: anastomosis

Contributor(s): Susan Rackard, Rosa Ragni

Introduction

Ureteric trauma - avulsion at the bladder

  • Avulsed ureters may be reimplanted (see ectopic ureter Ureter: ectopic).
  • Where the distal ureter is traumatized beyond repair it may be appropriate to consider uretero-ureteric anastomosis or the creation of a vesicular conduit by making a pouch from the bladder wall.

Ureteric trauma - other sites

  • Transected ureters may be repaired by end-to-end anastomosis.
  • Alternatives: anastomosis to contralateral ureter, ureteronephrectomy Ureteronephrectomy.

Uses

  • To re-establish urine flow from the kidney into the urinary bladder.

Advantages

  • Preserves renal function.

Disadvantages

  • If ends of ureter cannot be opposed without excessive tension, consider alternatives, eg creation of a vesicular conduit by making a pouch from the bladder wall, anastomosis to contralateral ureter, ureteronephrectomy Ureteronephrectomy.
