Supplies​ and Setup

Supplies

  • Suture board material (we use the Sim*Vivo suture material)​
  • Marking pen​
  • 24Fr Foley catheter​
  • Standard dish sponge​
  • Clipboard​
  • Thick non-absorbable suture (we use 2-0 nylon)​
  • Anastomosis suture (we use 2 4-0 monofilament absorbable sutures)​
  • Paper cup​
  • Scissors

Set up​

  • Cut a 1cm diameter hole in your suture material. This will be the transected bladder neck.​
  • Using your marking pen, mark your bilateral ureteral orifices (UOs) about 1cm diagonally away from your bladder neck in each direction​.
  • Fold your suture material in half and clip it into the clipboard with your bladder neck facing away from the clip and the UOs on the bottom side.​
  • Cut the end off of a 24Fr Foley catheter. This will be the transected urethra.​
  • Moisten your sponge and wrap it lengthwise around the catheter. Use your nonabsorbable suture to keep the sponge in place. This will be the periurethral tissue.​
  • Punch out the bottom of your paper cup. Cut off the top half of the rim of the cup as well. This will be the bony pelvis.​
  • Secure the pelvis and urethra to your clipboard using 2 rubber bands. This should be positioned such that the cut end of the urethra comes into contact with the bladder neck when the bladder neck is on a very mild amount of stretch.​
  • Prepare your anastomosis suture(s) as you like. We cut two sutures to 6-inch pieces and tie them together at their tails.
