Transurethral Resection of the Prostate (TURP) Model
Supplies
1. Porcine liver or similar animal liver
2. Dish tub or similar container
3. Surgery basin & kidney basins
4. Suction tubing & canister x 2
5. 2-0 suture on a Keith needle or similar
6. Water proof caulk sealant
7. Rubber grommet
8. Glad soup and salad container x 2
9. Binder Clips x 2
10. Duct tape
11. Steinmann pin x 2 or similar pin
12. Bovie pad or alligator clip
13. Laparoscope sheath 5-10mm
A. Take the glad salad container and cut a small hole in the
front with a exacto -knife or scalpel just large enough to fit
the rubber grommet. Seal edges of the grommet with some
sort of water proof caulk or sealant and allow to dry. Place a
small hole in the back left or right of the containers to allow
water to over flow from the container.
B. Take the second glad container which will act as a lid
and cut a small hole in the back large enough to fit a suction
tubing. This can be secured with duct tape. This tubing will
run to the suction canister to evacuate smoke when the model
is in use.
C. Place laparoscopic sheath inside the grommet.

A. Fold the left & right liver
segment up to create an inner
triangle effect representing the
prostate lateral lobes. Run 2- Keith
needle sutures through the segment
to secure and tie off leaving a long
tail on the left and right.
B. Once the liver is inside the
container, the resectoscope will go
inside the liver for resection.

electrocautery needs
Dual Ground Pad
Single Ground Pad
Alligator Clip Ground Cord
If using a Monopolar Resectoscope, you will need to ground
the liver by placing the liver on a electrocautery pad before
putting it in the glad container. If using a dual pad (A), it must
have liver tissue completely covering both sides for the pad to
work. I recommend a single pad (B) which has worked well for
us in the past.
Our biomed department made us a electrocautery grounding
alligator clip (C). They used the cord off of the grounding pad
and wired it to a banana plug which plugs into the alligator clip.
I purchased the alligators & banana plugs at Home depot.
To ground the liver with the clip just attached the alligator jaw
to the liver tissue and plug the cord into the bovie unit (D) .
If using a bipolar resectoscope , you do not have to ground the
liver at all but you will need to use Saline as your irrigation
fluid for it to work. Make sure to have plenty because you will
go through it very fast.
Steinmann pins
Black clips and suture tails
A. Use the black clips to
secure the suture tails on the
left and right of the container
which will hold the liver up.
Push one or two Steinmann
pins through the container and
into the lower section of the
liver coming out on the
opposite side. This will
stabilize the liver in the
container.
B. Turn the large surgical
basin upside down in the wash
tub and place the 2 kidney
basins on top. Tape the basin
around the edges with duct tape
to adhere it to the tub. Repeat
with the kidney basins. This
will raise the model to a height
that allows the resectoscope to
move freely without hitting the
edge of the tub. Tape the model
on all edges to secure it to the
basins.
A. Place the lid on the model and tape shut. Then
plug the rear suction tubing into a suction canister
to evacuate smoke. Place another suction tubing
inside the tub to suction the overflow fluids.
B. Insert assembled resectoscope and begin
resection.
In the past we have used a large surgical basin and also a pumpkin as our liver container. If you use a large
basin, the extra water causes the liver to float so you will need to glue or tape Styrofoam (A) to the bottom
and tack the liver down with T –pins. Secure the suture tails with clips (B)
The large basin required a lot of fluid so we decided to go to a smaller container. The pumpkin was a
seasonable items so this was only a good option in October.
